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.

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.

International Coatings Celebrates Diamond Anniversary – 60 Years!

 

StampBadgeUniformInternational Coatings, a leader in the development of textile screen-printing inks and a pioneer in the production of vinyl and urethane plastics, specialty coatings and adhesives, and traffic paint, is celebrating its 60th anniversary.

 

International Coatings was founded in 1957 by Herbert A. Wells, a chemist who previously helped develop Elmer’s Glue.  The company’s first products were custom industrial plastic and adhesive compounds.  Over the course of the next 60 years, International Coatings stayed true to its roots as a plastics compounder, pioneering numerous advancements in plastics, coatings and adhesives.  Today, International Coatings manufactures a wide range of branded and custom formulated plastic compounds for the apparel, traffic marking, water filtration, aerospace, sports and recreation, medical and adhesives markets worldwide.

 

The company entered the textile screen printing industry in the early 1960’s.  Many of the products developed by Mr. Wells and International Coatings remain industry standards to this day.  International Coatings’ high-performance Nylon inks and its classic low-bleed whites are industry favorites and have helped establish the company’s reputation for producing products that perform. International Coatings recently expanded its product offerings to include traffic paints and markings, meeting the growing demand for quality products within that industry.

 

“We at International Coatings are thrilled to celebrate 60 years of successes” said Stephen Kahane, International Coatings’ President. “We know that our growth, longevity and success come from our loyal stakeholders – our customers, distributor partners and employees. We are particularly proud that our Diamond Anniversary represents 60 years of continuous family ownership and management.”

 

Looking ahead,  International Coatings is committed to continued innovation, quality products, and outstanding service to our distributor partners and customers.  We recognize that  our success comes from customers’ success.

Building a Darkroom for Print Shops With Limited Floor Space

darkroomracksCan you suggest some approaches to building a darkroom for a screen-printing shop that has a limited floor space? This was a question posed by a Printwear reader, and here is Kieth Stevens’ response:

A booth can often be constructed of black plastic sheeting, which is relatively cheap to purchase. Choose a location close to the washout area to minimize exposure to light. Simply construct a 1′ x 3′ wooden frame and determine where to place the entry to the dark room. Staple the plastic to the frame and overlap some plastic to create the “door.” By overlapping the plastic sheets, it will minimize the light coming through during entry and exit. Also, be sure that the plastic cover reaches to the floor to block out light completely.

Another way to create a darkroom with limited space is to repurpose an existing room. For example, if the bathroom is not too small, turn it into a dual-purpose room. Repurposing a closet is also a great way to make use of the space you have.

Stand in the darkroom prior to use to be sure that there is no light leaking into the room. It may be necessary to block out minute shafts of light coming in through the bottom or sides of a door. Use plastic sheeting or light-blocking curtains to eliminate any light contamination. Consult your emulsion manufacturer as to which lights would work best and add a dehumidifier. In such a closed room environment, your screens will dry faster and more thoroughly when moisture content is controlled.
