Can I use sunlight to burn my screens if I run a small shop with minimal equipment?

Yes, I used to do this when our exposing unit was too small for the screen, or if the bulb had burned out and we couldn’t wait for a new one.

As an aside, this is a method I generally do not recommend, but if you have no other options, it is possible. To begin, use spray adhesive on the film and then press it onto the shirt-side of the screen to be burned. Make sure that the adhesive is sprayed evenly so as not to leave spots of heavier deposits on the film. The trick to this method is not to expose the other side of the screen (squeegee-side) while it’s being handled under the sun.

To avoid exposing the other side of the screen, I’ve used a cart on wheels that is at least as big as the screen. Cut a piece of foam that is at least as thick as the screen is and fits on the inside of the screen. Cover the foam with black T-shirt material, then lay the screen with the substrate side up and place the film in position. Don’t forget to put the film face down.

Now place a piece of glass on top of the screen that is at least as big as the screen and place some weighty object, such as a quart of ink, to push the glass, film, and screen down onto the foam beneath. Be sure to put the weight around the design on the film so that it can be exposed evenly by the sun. The weight will promote the best contact between all the layers. Now simply cart the screen to where you want to expose it.

Another tricky part is getting the right emulsion exposure. You may think that on a cloudy day, the UV rays aren’t passing through, but they are, and on a sunny day, they can be even more intense. Then there is the midday overhead sun which is much stronger than the afternoon sun in regards to the amount of UV available for exposure. I strongly recommend not using a pure photopolymer emulsion as those are just too sensitive for this technique. It may take some experimentation to get the exposure just right.

Mother’s Day Decorating: Screen-Printing Ideas

Mother's Day 2017

In a recent article posted by Printwear Magazine, John Levocz gives us some interesting screen printing tips and ideas for preparing designs this Mother’s Day.

 

For Mother’s Day prints think outside of the box and use specialty inks to create designs that shine. Moms love bling.

Glitter inks

Remember to print glitter inks through coarser mesh counts to let the glitter flake pop. Check with your ink manufacturer for the recommended mesh count. I recommend a 24 mesh count for the best results.

Shimmer inks

Shimmer inks use a finer metallic particle and can be printed through higher mesh counts (86–120 count) to create a shimmer look.

Remember when printing glitter or shimmer inks to adjust your dryer to achieve full cure temperatures. The metallic flake in glitter and shimmer inks will reflect the heat away from the garment. Usually, a slower belt speed will do the trick. Remember to test before going into production.

Reflective inks

Reflective prints also give designs pop during low light conditions when hit by a bright light. Check with your ink manufacturer for proper mesh counts and curing temperatures as a variety of different reflective inks are currently on the market.

Gel-gloss inks

Overprint gels are another way to enhance standard prints by adding shine or a wet look to a print. Most gels can be printed through an 110 mesh count screen. Remember to reach the recommended full cure for optimum clarity of the finished gel print.

Foil adhesives

Using foil will help you create a shiny design in an almost endless color pattern. Most foil adhesives are printed through a 74–110 mesh count depending on the design.

All of the above inks and methods can be used in creating designs for shirts as well as hats, cotton gardening gloves, cloth calendars, and aprons for Mom’s special day. By using your imagination, you can create endless designs on a variety of substrates.

How do I avoid the white spots that pop up on my garment after curing?

Printwear Questions (6)

This was a question posed by a Printwear reader, and here is Kieth Stevens’ response:

This issue happens at times when using a white underbase ink that contains a blowing agent. The blowing agent helps improve opacity and control dye migration. However, the blowing agent contains microbeads that inflate when cured, and some may pop, leaving a hole in the inks printed on top. To help mitigate this issue, use a quality white ink that does not contain a blowing agent, or flash the white a little longer to get the blowing agent to begin puffing earlier. Over-curing the ink may be another cause for the popping as well.

What kind of basic tools should I own for cleaning my screens off?

Carboard-Ink-Scoop

Cardboard soaking oils from plastisol ink

A reader posted this question on Printwear. Here’s a quick tip from Kieth Stevens:

Although popular, it’s best to stay away from cardboard scrapers as they tend to soak or absorb the liquid portion of the inks. Some screen supply stores offer specially designed plastic ink scrapers. These plastic scrapers feature rounded corners so they avoid harming the screens.

As far as the cleaning liquids go, there are many available that do a great job. You can usually use an ink degradant on the screen to help break down the ink chemistry. However, they seem to be greasy in nature, so once you have cleaned the screen with a degradant, it may be difficult to get tapes to stick to the screen. It is often necessary to add a final cleaning using a more aggressive solvent to achieve a clean, dry screen.

The Best Place to put Your Washout Booth

InkWashStation (Rev)Where is the best spot for a washout booth in my production layout? This was a question posed by a Printwear reader, and here is Kieth Stevens’ response:

Typically, the best spot for a wash-out booth is nearest to a water source. However, the best spot for your booth can depend on what you are washing out. If you are washing out emulsion after exposing the screen, you want the washout booth set up close by to avoid further exposing the screen to outside ambient light before washing it out.

However, if the washout booth is going to be used just for reclaiming screens, then it is best located closest to a convenient area for reclaiming. If the washout booth is used for cleaning screens after printing with a water-based ink, then locating it closest to the print area would be best.

Remember, it can be very noisy when blasting a screen with water pressure, so it’s also generally a good idea to make sure the booth isn’t too close to offices, the breakroom, or anywhere in the shop where you want to avoid excessive noise.

Repairing Torn Screens

screenTear

Is it possible to reclaim a screen that has a small hole or two in it, or is it not worth the work? This was a question posed by a Printwear reader, and here is Kieth Stevens’ response:

I have used cyanoacrylate glue as an emergency way to prevent a tear from stopping production. However, I usually make a backup screen as soon as the repair is made so that production is not stopped if the repair fails.
