Before you can burn a screen, you need a film positive — a printed image on transparent film where the design area is opaque black and blocks UV light during exposure. This step is what connects your artwork to your finished stencil, and it is one of the most commonly skipped topics in startup guides.
Step 1 — Inkjet Film
You print your artwork onto waterproof inkjet film, not regular paper. The film has a coated side that holds dense, UV-blocking ink. Thin ink density is the most common cause of pinholes in screens. Use
AccuJet waterproof inkjet film with
AccuInk for maximum opacity on every print.
Step 2 — Film Output Printer
A dedicated inkjet printer loaded with UV-blocking ink is the standard for film output. The
Canon IX6820 and
Epson T3270 are the two most common setups for screen printing shops. Both produce dense, sharp positives suitable for spot color and halftone work.
Step 3 — RIP Software
A RIP (raster image processor) drives your film printer at the correct ink density and resolution.
CADlink FilmMaker is the industry standard for screen printing film output — it controls dot gain, density curves, and linearization so your positives burn clean, consistent stencils every time.
Pro Tip: Print Double-Sided for Maximum Opacity
If your positives are not dense enough to fully block light, print two copies and tape them emulsion-to-emulsion. This is a quick fix while dialing in your printer settings. Long term, correct ink density settings in your RIP software and the right film/ink combination will eliminate the need for it.
Choosing Your Exposure Unit: LED vs. UV Bulb
The exposure unit burns your emulsion-coated screen using your film positive as a mask. The quality of your exposure unit directly affects stencil sharpness, halftone reproduction, and edge definition. There are two types: UV fluorescent bulb units and LED units.
UV Fluorescent Bulb Units
Lower upfront cost. Requires warm-up time before each exposure session. Bulbs degrade with use — exposure times must be recalibrated as bulbs age. Bulb replacement adds ongoing operating cost. Suitable for low-volume shops or very tight startup budgets.
LED Exposure Units Recommended
Higher upfront cost, significantly lower lifetime cost. Instant-on with no warm-up. LED elements last far longer than UV bulbs with no degradation in output. Sharper edge definition and better halftone reproduction than bulb units. Consistent exposure times from year one to year ten.
If a vacuum-top exposure unit is within your budget, it is worth the upgrade. A vacuum top presses the film positive flat against the emulsion-coated screen during exposure, eliminating the light scatter that causes loss of fine lines, halftone dots, and small text. Without a vacuum seal, light can bend around the edges of your artwork and soften details.
Setting Up Your Screen Room (Darkroom)
Your screen room is the area where you coat screens with emulsion, dry them, and store them before exposure. It does not need to be a full photographic darkroom — it needs to be light-safe, temperature and humidity controlled, and dust-free. This is where most home-based and garage shops cut corners early and pay for it later in failed screens.
Light Control
Replace any white overhead bulbs with yellow-spectrum safe-light bulbs. Yellow light does not activate the photo-sensitive emulsion, so you can work with coated screens safely. Block all UV light from windows and door gaps. Even brief exposure to bright daylight can begin to harden your emulsion before you are ready to expose.
Temperature and Humidity
High humidity dramatically slows emulsion drying and can cause emulsion to absorb moisture, leading to weak or tacky coatings that do not expose cleanly. In San Antonio and South Texas summers, a dehumidifier in your screen room is not optional — it is necessary. Target under 50% relative humidity and 65–75°F for consistent results.
Where to Set It Up
Common options: a bathroom (good humidity control, easy to seal light), a laundry room, a spare closet, or a walled-off corner of your garage with light-blocking plastic sheeting. The space does not need to be large — just big enough to hang or rack coated screens horizontally while they dry.
Screen Drying Cabinet — Worth the Investment
A screen drying cabinet uses convection heat and fans to dry emulsion-coated screens in as little as 15 minutes. Without one, drying screens horizontally at room temperature in Texas humidity can take hours — sometimes all day in summer. If you are printing on any kind of schedule, a drying cabinet pays back in time within the first week of use.
Mesh Count Quick Reference
Screen mesh count refers to the number of threads per square inch. Higher mesh = finer openings = less ink deposited. Choosing the wrong mesh is one of the most common beginner mistakes — too low and the print is muddy with excessive ink, too high and you cannot push enough ink through for coverage.
| Mesh Count | Best For | Notes |
|---|
| 110 | White underbase, spot color, block text on dark garments | High ink deposit; good starting mesh for beginners printing on darks |
| 156 | General purpose spot color, most standard jobs | The jack-of-all-trades mesh; if you can only stock one count, this is it |
| 200 | Semi-detailed prints, water-based inks | Good balance of ink deposit and detail; works well with water-based formulas |
| 230 | Fine detail, thin lines, smaller text | Less ink deposit; not for heavy plastisol or white underbase work |
| 280–305 | Halftones, CMYK, simulated process, ultra-fine detail | Advanced work; requires well-tensioned frames and precise exposure |
For a deeper breakdown including thread type, frame material, and halftone-specific recommendations, see our complete mesh count guide.
Choosing Your Emulsion: Diazo vs. Presensitized
Emulsion is the light-sensitive coating that becomes your stencil. It comes in two main types, and the difference matters for beginners. Using the wrong type — especially presensitized emulsion before you have a well-controlled darkroom — is a frustrating and expensive way to learn.
Diazo (Dual-Cure) Start Here
Requires mixing a diazo sensitizer powder into the emulsion base before first use. Takes longer to expose, which gives you a wider margin for error — if your exposure time is slightly off, the stencil is more forgiving. Recommended for beginners. Chromaline CP Tex and similar diazo-based emulsions are what most new shops start with.
Presensitized (Pure Photopolymer)
Pre-mixed, no sensitizer required. Exposes faster and is extremely sensitive to UV light — even ambient daylight through a window on a cloudy day can begin to expose it. Very unforgiving in a poorly controlled darkroom. Better resolution and fine detail, but not recommended until you have a well-sealed, humidity-controlled screen room and consistent exposure times dialed in.

Your First 90 Days: Skill Building Before Selling
The most common mistake new screen printers make is taking customer orders before they have consistent process control. Print quality problems on customer orders damage relationships and generate reprints that eliminate your profit margin. Before taking paid orders, develop consistency in screen coating, exposure, registration, and cure on your own time. Print for friends, family, and yourself. Solve the problems with your own materials before you have a deadline and a customer waiting.
Specifically: learn to expose a screen correctly (no pinholes, no underexposure) on your emulsion type, achieve consistent ink deposit and coverage on dark garments with a white underbase, and verify full cure on every piece with a stretch test. These three skills cover 80 percent of the problems that will cause customer complaints.
What Can You Earn? A Realistic Pricing Guide
Screen printing profit comes from the gap between your cost per print and your sell price. The math is straightforward once you understand the inputs. Here is a realistic example for a beginner shop taking on a standard order.
Sample Order: 72 Shirts, 2 Colors on Dark Garment
Blank shirts (wholesale)
~$3.50
per shirt
Ink + screen cost
~$0.75
per shirt at 72 pcs
Your sell price
$10–$13
per shirt all-in
Order gross margin
$430–$640
before overhead
Pricing increases with smaller orders (less than 24 pieces) and more colors. Specialty inks — glow, reflective, metallic — command a per-screen premium. As your volume grows and your setup time per job decreases, margin improves. Most manual press shops become profitable within their first 6 months at part-time volume.
Pricing varies by region, customer type, and job complexity. Research what local competitors charge. Do not undercut on price before you understand your actual cost structure — early low-price wins often turn into losses when reprints and rework are factored in.
Finding Your First Customers
Equipment and skill are only two-thirds of the equation. The shops that grow fastest know exactly where their first orders are coming from before the press is even bolted together. Here are the highest-probability markets for a new screen printing shop.
Sports Teams and Youth Leagues
Sports teams consistently need uniforms, warmup shirts, and spirit wear every season. They also consistently wait until the last minute and struggle to coordinate sizes and payments. If you can organize the order and deliver on time, you become the go-to printer for that program year after year.
Local Small Businesses and Restaurants
Staff uniforms, promotional shirts, and grand opening merchandise are recurring needs for any local business. Walk in with a sample print of their logo — a shirt in hand closes orders that an email never will. Target restaurants, gyms, salons, and trades businesses in your area first.
Events, Reunions, and Fundraisers
Build a calendar of every local event, race, school function, family reunion, and community fundraiser you can find. Outreach before the event is scheduled wins orders before they go to a bigger shop. Holiday and seasonal events are on the same calendar every year — build your pipeline 6 to 8 weeks ahead.
First Responders and Organizations
Fire departments, police departments, EMS services, and military units are consistent buyers of custom shirts for training, charity events, and morale gear. They tend to reorder and refer. A personal introduction to a department contact is more effective than any advertisement.
Tag Every Order for Free Referrals
Attach a business card to every shirt you deliver — especially for events and group orders where dozens of people will see and wear the product. Someone in that group is always a buyer or knows one. A simple card with your phone number and a quality guarantee on the back will move through a shirt drawer and get passed along long after the order ships.
Building Your Supply Relationship
Your ink, emulsion, and chemical supplier is one of your most important business relationships. A good supplier answers technical questions, has reliable stock of the products you depend on, and ships fast enough that a supply shortage does not shut down your press. River City Supply has been the primary screen printing supply relationship for hundreds of Texas and nationwide shops since 2006 — authorized distributor of every brand we carry, with same-day shipping before 3:30 PM CT.

A professional multi-color operation with conveyor dryer, quality manual press, and full ink inventory typically runs $10,000 to $25,000. Automatic press setups start at $50,000 and scale to $200,000+. Equipment financing is available through River City Supply for qualified buyers —
see financing options.
Can I start a screen printing business at home or in a garage?
Yes. Many successful shops start in a garage, basement, or spare room. You need enough space for a press (roughly 6 to 8 feet in diameter for a 4-color), a dryer run of 6 to 10 feet, and a separate light-safe area for coating and drying screens. A 2-car garage works well for a complete single-operator setup. You will also need access to water for washing screens. Check local zoning rules before taking customer deliveries at your home address.
What do I need to buy first when starting a screen printing business?
In order of priority: (1) a manual screen printing press with at least 4 color stations, (2) a flash dryer, (3) an exposure unit, (4) a conveyor dryer, (5) a film output printer and inkjet film for creating positives, (6) starter ink kit with white, black, and primary colors, and (7) emulsion, screens, and chemicals. A conveyor dryer is the most commonly skipped item that causes quality problems — budget for it early.
How much can I charge per screen printed shirt?
A 1-color print on a standard T-shirt typically runs $5.50 to $9.00 per shirt depending on quantity. Multi-color work on dark garments with a white underbase runs higher. A 72-piece order at 2 colors on a dark shirt might be priced at $10 to $13 per shirt all-in including the blank. Specialty inks such as glow, reflective, or metallic command an additional per-screen premium. Most screen printers use quantity tiers: higher per-shirt pricing for small orders, lower for bulk.
Do I need any certifications or licenses to start a screen printing shop?
Business licensing requirements vary by location — most cities require a general business license and a seller's permit or sales tax ID. Screen printing itself has no federal certification requirements, but your local area may have environmental regulations on chemical storage and discharge. Contact your local city or county business office for specific requirements in your area.
Do I need a washout booth to start screen printing?
A dedicated washout booth is not required on day one but is strongly recommended. Without one, you can use a utility sink or outdoor hose. Always fit a mesh trap on any drain used for screen washing to catch emulsion solids before they reach your plumbing. A washout booth keeps your shop cleaner, protects your drain system, and makes screen reclaiming significantly faster as your volume grows.
Shop washout booths →What software do I need for screen printing?
You need two types of software: design software and output software. For design, Adobe Illustrator is the industry standard for building vector artwork and color separations. For film output, a RIP software such as
CADlink FilmMaker ensures your film positives print at the correct density and resolution for clean screen exposure. Without proper RIP output, your positives may not fully block UV light, which leads to pinholes and underexposed screens.
Should I get an LED or UV bulb exposure unit?
LED exposure units are the current industry standard and the better long-term investment. LED units last far longer than UV fluorescent bulbs, use significantly less energy, and produce sharper stencil edges with better halftone reproduction. UV bulb units cost less upfront but bulbs degrade over time, requiring periodic replacement and recalibration of exposure times. If your budget allows it, start with LED.
Shop exposure units →How long does it take to learn screen printing well enough to sell professionally?
Most people can produce acceptable single-color prints within a few hours of first practice. Producing consistent, professional-quality multi-color work on dark garments typically takes 30 to 90 days of regular practice. Mastering registration, exposure, and color mixing to a professional commercial standard takes 6 to 12 months. Many successful shops start with simple work and expand capability as skills and equipment improve.
What is the best screen printing press for a beginner?
The Vastex V-1000 and V-2000 series manual presses are industry-standard starting points for new shops. They are built to professional standards, available in 4 and 6 color configurations, and designed to accommodate growing shops that will eventually add more stations. River City Supply is an authorized Vastex dealer — call (512) 454-0505 for a new shop equipment consultation.
What screen printing inks should I start with?
Start with plastisol inks — specifically a starter kit that includes white (high-opacity for dark garments), black, and a set of standard process colors for mixing.
Inktek LB series plastisol inks are professional-grade, economical, and available from River City Supply with same-day shipping. Water-based and discharge inks require more equipment and process control — add them after you have mastered plastisol.
