Rubber Top Aluminum Platens

Share on Facebook0Tweet about this on Twitter

Rubber top aluminum screen printing platens have been an addition that some screen printers are adding to their businesses. In general the aluminum platens tend to last longer than the wood platens and the aluminum is easier to clean. Every flash cure increases the temperature of the wood or aluminum platens. While this causes the wood to change shape over time, the aluminum will retain the heat, but maintain it’s shape. This added heat on the aluminum platen can cause the ink to prematurely cure. However, the rubber tops can be added to help dissipate the heat faster. The rubber tops also give the print a softer finish, making the plastisol ink feel more like a waterbase ink screen print.

While the aluminum platens are more efficient, the rubber tops over time will need to be replaced. Make sure to buy replacement rubber tops and when glueing the new rubber tops onto the platen use a high quality glue and try to get the rubber as seamless as possible.

If you’ve already made the switch to aluminum platens then it could be beneficial to try printing with rubber tops. If you are happy using wood platens, then by all means, stick with what works for you.

  • 1/4″ Solid Aluminum & 1/8″ Soft Top Rubber is an industry standard on major automatics.

Eliminating Scorching When Screen Printing

Share on Facebook0Tweet about this on Twitter

Scorching your screen print is a common mistake for people newer to screen printing. Your garment will literally get burn marks where it has been overly cured, which can result from inconsistent and high dryer temperatures. Purchasing a Workhorse Powerhouse Quartz Dryer would be ideal to eliminate this problem since their technology and craftsmanship makes it one of the best dryers on the market. The Quartz Dryer warms up in seconds and maintains it’s set temperature, ensuring consistent performance. However, if you already own a good quality dryer than most likely your temperature setting isn’t ideal for your type of print and you are to blame. ūüôā

Below are some different techniques that will help you pinpoint what’s scorching your screen prints:

  • The ink deposit required for a white shirt, instead of a black shirt will cure at different temperatures. More ink is required on a black shirt, because of the white under-base, so that means that you would cure that shirt at a higher temperature.
  • White shirts don’t hold as much heat as darker shirts, so it more than likely that your scorch marks will appear on the white shirts. You want to get the shirt as hot as possible without scorching it, so this is where you need to test out your prints. We suggest that you have a few spare garments to test print and wash before full production.
  • For thinner ink deposit on a white shirt you can cure at a temperature of about 290-300 degrees Fahrenheit. For a standard ink deposit on a white shirt you are usually safe with about 300-310 degrees Fahrenheit.
  • Most athletic jerseys with thicker ink deposit require 340-350 degrees Fahrenheit.
  • Some heat sensitive fabric like spandex, or some workout wear will need a low cure additive like 3804. In this case usually you can correctly cure at 280-285 degrees Fahrenheit.

Another product that is helpful is Tekmar Scorch Remover . Scorch Remover will remove light-medium burn marks, or sun discoloration. You simply spray the remover onto the burnt or discolored areas of the shirt, and run the shirt back through the dryer.

What Makes a Good Screen Print

Share on Facebook0Tweet about this on Twitter

What makes a good screen print? Most screen printers will feel a person’s printed garment first and then take a good look at it second. Below are some tips to help ensure that your screen prints are successful:

Printed by L.A. Airline

                Printed by L.A. Airline

  • The feel of the print should match the feel of your fabric, so that it feels as though you are wearing a plain shirt.
  • The garment should wash well, shouldn’t crack and be fade resistant.
  • The lines (artwork) should be clean and crisp.
  • Use the right types of inks, additives, and or specialty materials for your design and garment is imperative.
  • The speed, angle and pressure should be consistent for every print. Your own repeated technique/system will be what makes your jobs easier and consistent.
  • Riding the blade of the squeegee on the print edge, through the proper mesh will help you get the cleanest print. Some argue that this is harder to do manually, but again it just goes back to your personal print method.
  • 160 mesh count should be your most common printing mesh. The mesh count tends to see the biggest mistake made when screen printing.
  • Under or over-curing the ink is also another common problem. Also do a test print and be sure to fully cure your ink to prevent cracks.
  • Knowledge and understanding of off-contact printing is ideal.
  • Using a T-square to square the image up properly on your garment will also help for consistent images on the garment.
  • Make sure you stir your ink! Plastisol ink tends to get thicker over time, so always stir it and ensure that it is creamy and smooth. If your ink needs to be thinned then add in an additive.
  • Use screens that are properly/correctly tensioned.

Hopefully these tips will help you and leave you with some amazingly good screen prints.

Film Output Systems

Share on Facebook0Tweet about this on Twitter

Film Output Systems are an essential key to any screen printing shop. It’s this major step that allows you to transfer your artwork to the screen. When you have turned your design into a film positive, you will print it with black ink on clear waterproof film. This positive print will block out the light during the exposure process. If you don’t have a clean, dark film positive you will lose the crisp, clean look of your design. The darker your positive the better the image will wash out on your screen, and this is why your film output system is crucial.

Epson printers are the best printers on the market! These printers will ensure a dark ink positive and come with AccuRIP software. Since these printers only print black ink they are fast, reliable, and can print halftones. Below are the Epson Film Output Packages that we recommend at Mclogan’s:

Epson 1430 All Black Ink Film Output Package¬† The 1430 can print 13 inches wide and comes with 6 black ink cartridges, AccuRIP software and 200 sheets of waterproof film. Easy to set up, and affordable while still offering Epson’s amazing quality prints.

How-To Screen Print: Degreasing Screens

Share on Facebook0Tweet about this on Twitter

The process of degreasing your screen with Franmar Degreaser to remove all the grease, dirt, dust and oils before putting on your emulsion is crucial. This step is important and one that some beginner screen printers don’t do. If this is a step that your normally skip, then your emulsion will not adhere to the screen causing pinholes to your design. If there is any grease, or oil on your screen your emulsion will just fall off of the screen, leaving you with a poor image resolution. It’s also just as important to have a dedicated scrub pad just used for degreasing. When you properly clean and rinse your screen then you will have complete adhesion, a great image quality, and a stencil that will last during your production hours.

Here’s our YouTube video showing how to properly degrease and rinse a screen.

Screen Printing How To – Applying Block-Out Tape

Share on Facebook0Tweet about this on Twitter

Block-Out Tape is solvent resistance, conformable to screen corners, highly adhesive yet easy to remove without damaging your screen. Once you put your emulsion on the screen, using block-out tape is your next step.¬† Blue Block-Out Tape is essential for every screen print shop. You’ll use it to cover the 4 sides of the frame/screen and corners, front and back to block ink from passing in unwanted areas. Hide the registration marks with the clear tape, so that you can still register your artwork.

Watch this quick video to further explain how to use block-out tape.

Off Contact Screen Printing Set-Up

Share on Facebook0Tweet about this on Twitter

Off contact screen printing is the space between the substrate and the printing side of your screen. This type of printing method allows the screen to only touch the garment lightly when the squeegee is pressing the ink through the screen. Off contact height levels are determined by the fabric of your garment and can range anywhere from an 1/16 of an inch to a 1/4 inch.

Watch McLogan’s video to see how to set up your screen for off contact printing.
