Which stencil system is better, capillary film or direct emulsion?

They both work very well. What's important is what will work best for your application. Direct emulsions are generally more resistant to rough treatment due to abrasion and solvent resistance. Films will usually yield sharper line edge definition.

How can I tell if my screen is underexposed?

Touch the inside of the screen during washout. If the stencil is slimy or you get color on your finger, it is a sure bet that it is underexposed. Use an exposure calculator to determine your proper exposure calculator.

Why does my dual cure emulsion break down with water-based ink?

Many people in our industry believe the "dual" in dual cure means that this emulsion is resistant to both solvent and water-based inks. Although many dual cure emulsions are resistant to both inks, this statement is not correct. The "dual" in dual cure means that the emulsion uses two sensitizers. One is already in the emulsion before mixing, and the other is usually a Diazo that is added to the emulsion by the user. For example our UDC-HV dual cure emulsion is not recommended for water-based inks, but our UDC-2 and UDC-ACE are recommended for both water and solvent-based inks.

Plastisol Ink Questions

How do I print on polyester shirts without getting dye migration?

"Dye Migration" occurs when garment dyes migrate up into the ink film, changing the colors of the printed inks. You may have seen red 50/50 t-shirts printed with white ink. That printed white ink may have turned a pinkish color over time due to "dye migration". 

  • To prevent dye migration use a low bleed series plastisol ink; these inks have dye blockers in them to make it difficult for the dyes in the shirt to penetrate through the ink. 
  • There are also some low cure inks that do not require as much heat to cure the ink which helps tremendously; because heating the dyes in the shirt is what makes the dye migration start. Excalibur's 1550 Series is a great option for a low cure ink.
  • Use a low mesh screen to lay down a thick layer of ink; we recommend an 86 mesh screen.
  • When coating your screens with emulsion do multiple passes with the rounded side of your scoop coater.  You want to make a tall ink deposit; so with every pass you are laying down a good amount of ink.  Depending on which emulsion you are using the recommended number of layers can vary.
  • Use a high solid content emulsion.  By using a thicker emulsion you can achieve a taller ink deposit. A good emulsion for this is Murakami HS High Density Emulsion.
  • Print an underbase and or do a print flash print to get multiple layers of ink. 
  • Do not over cure the inks!  Heat is what causes this so you only want to run your dryer the require temperature to set the ink and then get it out of the conveyor.
  • Always test a shirt before proceeding with a long run; dye migration can take hours and in some cases days to show up.

What causes plastisol ink to build up?

There are a few causes of ink build up on the under side of screens; type of inks being used, mesh tension, thickness of mesh thread, emulsion over mesh (EOM).  First check to make sure the plastisol ink series you are using is made for wet on wet printing (WOW).  Next check your screens and make sure they are tensioned to the mesh specifications.  Low tension will cause build up; and increasing squeegee pressure is what most printers do to compensate for the poor print; however too much pressure amplifys build up in WOW printing.  Thread thickness plays a key role in WOW printing; you want to use the finest mesh available with a good open area (if properly tensioned) you should be able to back off your squeegee pressure and just let the inks fall through the mesh without jamming the mesh into the shirt.  Emulsion coating plays a role as well; make sure you have a good coat of emulsion on your screens; depending on the thickness of the thread in your mesh you may need to do multiple coats of emulsion on the print and squeegee side of the screen.

The simple easy fix is adding process clear to your inks to lower your inks viscosity and remove some of the tackiness; or spray Sprayway 945 Silicone Spray on the underside of the screens.

How can I tell if plastisol ink is fully cured?

The definitive test to determine if plastisol inks are cured is a wash test, which is washing the garment in hot water with a strong detergent. Generally it will take from 5-10 washings to fully test the cure, but if the ink is seriously under cured, the print will show deterioration after only 1-3 washings. There are two other tests commonly used to check ink cure. The most popular test is to stretch the print about 2/3 of the total stretch of the T-shirt. If the print cracks badly and does not retract when the fabric is released, the ink is probably under-cured. The stretch test does not always work on thick deposits of ink, such as with on athletic jerseys, where the top layer of ink may stretch but the ink deep down in the fabric may be under-cured.

Another test for curing can be done by placing a few drops of ethyl acetate onto the back of the ink on the inside of the garment. This spot of ink is then placed onto an area of unprinted garment and burnished or held tightly together for two minutes. If there is a transfer of ink to the unprinted area, the ink is not fully cured and the garment should be run through the dryer again. Like the stretch test, this test is not always accurate. Ethyl acetate is a fairly hazardous chemical.

If the ink is under cured, you can run it through the dryer again and complete the cure.

Where should I store my plastisol inks?

Store in closed containers at 65 to 95 degrees F.(18 to 32 C.). Prolonged exposure to temperatures above 95º F (32º C) can cause the ink to start to gel while it's still in the container.  Keep out of direct sun light.

How can I increase the opacity of my plastisol inks?

Add 0.5 to 1.0 % M00010 Thickener #3 to increase the viscosity of the ink.  The ink will set higher on the garment surface and give more opacity. Thickener #3 must be thoroughly mixed into the plastisol ink.

What do I need to screen print on Nylon?

To print on nylon and lycra fabrics you need to add a catalyst to your exisiting plastisol inks.  The Excalibur X150 Nylon Bonding Agent works as a bonding agent to adhere the ink to the fabric.  This product is mixed in a ratio of 15% catalyst to 85% plastisol ink. 

How do I screen print Puff Ink?

  • Use Printers Choice Puff Additive(25% - 40% by weight).
  • Use coarse-mesh fabric (38-86) for high puff and finer meshes (110 -125) for lower and detail puff.
  • Use a “thick” stencil/ emulsion screen. Murakami HS Photopolymer Emulsion
  • “Stack” the print (print - flash-print) for extra high effect.
  • Print an under base so the puff has a base plate to push upward instead of down into the fabric.
  • Do not cure too hot or too long, as puff can collapse under too much heat.
  • When printing large solids, use half-tone dots/mezzotints to avoid “puckering.”
  • Always print puff as the last color.

How much squeegee pressure should I use?

The less pressure is better! Only use what you actually need.  Too much pressure can cause ink build-up, dot gain/ smearing, excessive penetration (less opacity), reduced ink mileage.  You can achieve less pressure by keeping your screens tension level high, using a thinner mesh with a more open area like the Murakami S-mesh, thinning your inks down with curable reducer or process clear.

How do I print on Spandex or stretchy materials?

Spandex and other stretchy materials can be printed on with your traditional plastisol inks, but you need to add stretch additive to the ink,  stretch additive gives the ink more elasticity and the ability to flex with the garment. 

Why are my inks cracking or washing out when the garments are laundered?

Under cured!  Plastisols must hit 325 Degrees for a minute to a minute and half.  In some cases it may be one color washes out and the other color stays in on the shirt just fine.  This can happen for a number of reasons:

  • Some inks are thicker or thinner than the others; the thicker the ink is the longer it requires for a full cure.  (White inks, and metallic inks are usually thicker and the first to wash out if it is under cured.)
  • Lower mesh on the color that washed out causing the ink deposit to be thicker; and the heat not fully curing all the way through to the bottom of the image.
  • Over loaded ink with an additive; always check how much of any additive you can add to any ink before mixing.
  • Multi layers of inks; when multiple colors are printed over one another the heat takes longer to penetrate all the way through to the bottom ink color. 

Film Positive Questions

What are the benefits of a waterproof film?

​Waterproof films offer a number of advantages. They dry faster after printing. AccuArt3 and AccuBlack have a special coating that helps to receive the dye-based ink and help it to dry instantaneously. This means there is little to no waiting for positives to dry, and no fear of smearing or marring the image during handling. The waterproof nature is also a benefit in the screen room. If the positive gets wet, the image will not be ruined. Simply allow the positive to dry and re-use.

What side of the film do I print on?

​With all AccuArt products, you need to print on the coated side of the film. With AccuMark, it’s easy to determine the proper side. With AccuArt3 and AccuMark, the coated side has a very matte, slightly frosty appearance. The opposite side is very shiny. With AccuBlack, the differences are more subtle. The coated side has a duller, more matte appearance. To the touch, it appears to have a bit more tack versus the smooth and shiny opposite side. Be sure to load the film appropriately into your printer. For front tray-feed printers, load the film coated side down. For back-feed printers or if you’re using rolls, feed with the coated side facing up.

Do I need any special software to use these films?

For the most part, no. AccuArt inkjet films are designed to integrate into your graphics work flow. The only software you may need to buy is a RIP (raster image processor), if you’re not already using one. The RIP is helpful in creating color separations and also helps to improve print quality. We recommend the AccuRIP Black Pearl. ​

Why do I have to use dye-based inks with these films?

​Dye-based inks are recommended because they actually penetrate into our special coating on the film. This aids in improving density, speeding up dry times and is integral in the waterproof nature and permanence of AccuArt and AccuBlack. Pigment based inks do not commonly work as well because they tend to remain on the film’s surface. This usually will result in longer drying times, a lack of density and lesser durability (ink is more likely to scratch off or run in wet/humid conditions).

I tried printing out a positive and the image quality is not good. What am I doing wrong?

​This could be caused by a number of factors: 1. Check to see that digital artwork is of adequate resolution. Line art should be at a resolution of 1200 dpi. Color or grayscale art should be at a minimum of 300 dpi. 2. Check to see that you are printing at a proper resolution. Positives should be printed at a minimum of 720 dpi. 1440 dpi is recommended. 3. Be sure to choose a film media from your printer properties menu. This tells the printer what type of media is going through the printer. 4. Are you using a RIP? The RIP typically will improve print quality, resulting in smoother line edges and clean halftone dots if you’re doing separations. The AccuArt films can handle halftones up to 65 lpi.

What are the advantages of positives created by inkjet printers?

Inkjet positives offer a number of advantages. 1. Equipment cost is a lot lower. Inkjet printers are relatively inexpensive, and typically cost a fraction of what laser printers and imagesetters cost. 2. Accu Products are clear films with excellent density, which means that they will properly expose your screen. Vellums and some other media, are more opaque in nature, which means the light will not transfer as easy during exposure. This will sometimes result in underexposure. Another concern is often the toner (black) areas of the positive are not opaque enough to block out light. This may cause light to transfer through these areas, leading to improper exposure which may yield imaging and washout problems. 3. Inkjet printing is a cold process. With laser and thermal printers, heat is involved in the process which can cause image distortion and shrinkage of the media. Yellowing is particularly evident with thermal printing. ​

Are my inkjet positives reusable? How do I store inkjet positives?

Positives made with AccuArt inkjet films can easily be archived for later use. For best results, store the positives in a cool, dry area and interleaf with clean newsprint. ​

Why is my inkjet film positive not printing dark enough?

This could be caused by a number of things: 1. Make sure that you printed on the coated side of the film. 2. Did you use the proper print settings? For best results, print at a resolution of 1440 dpi and use a print setting for film media. You may need to experiment to find the best media setting for your printer. 3. If you’re doing positives/negatives, print with black ink only versus color. If you’re in color mode, sometimes the printer will mix the colors to make black opposed to getting a pure black ink print. 4. Make sure that you’re using dye-based inks. The dye-based inks penetrate into the film, yielding better density. Pigment based inks will remain on the surface which will typically yield less density. ​

Emulsion Questions

Which Emulsion is best?

We get asked this all the time and there is no way to answer without the follow up question; "what inks are you printing with?  how much detail is in your designs?" 

Our most popular emulsions are Chromaline Chromablue and Murakami HV and Murakami HVP.  All three of these emulsions are pure photopolymers, with fast burn times, hold up great to plastisol inks, and reclaim easily if exposed properly. While photopolymers are excellent for fast exposure times and printing plastisol; they do not pick up as much detail as some of the dual cure emulsions out there.  Dual cure emulsions have a diazo added to them, and by their nature expose much slower than a photopolyer.  While dual cure emulsions expose much slower; they are more durable, pick up more detail, and have a wider range for over and under exposing times. 

If you are printing with water based inks you have several options:  Chromaline CP-Tex (our most popular), Murakami HV & Murakami HVP, Murakami SP-1400, and Murakami Photocure Pro.  While all these emulsions are made to hold up to water based inks, for long runs emulsions can require the help of an emulsion hardener.  Murakami MS Harder, and the more permanent Murakami Hardner A&B

How long should I expose my screens?

No one can tell you your exposure time and be 100% correct.  Every light source is different, bulbs vary, distance from the bulbs, coating techniques and thicknesses.  The only way to get your emulsion dialed in on your light table is guessing and wasting time and emulsion; or just get an exposure calculator.  This tool allows you to over expose one screen and it will tell you your correct exposure time.
