Q: I am considering upgrading my exposure unit to LED. What are the advantages of LED compared to non-LED units in the marketplace?

A: LED exposure units continue to be sought after technology because of the many advantages they offer. Let’s take a closer look.

  • LED units power up instantly, therefore, no warm-up time is needed. Non-LED units have to warm up before they are fully functional. For this reason, many shops leave it on all day so there is no wait time before each use. LEDs are ‘instant on’ and ‘instant off’, yet no power is consumed between each usage. This also lessens its overall power consumption.
  • Lower energy consumption means LED units are more efficient to operate on a daily basis. You’ll enjoy energy savings on electricity use and be doing your part by using a more ‘green’ solution.
  • LED units require little to no maintenance and use long-lasting bulbs that do not fade or weaken over time (unlike traditional bulbs). Also, with an LED machine, there should be little to no noticeable light degradation. The light emitted is as good at the first second as it is at the end of the LED bulb’s life.
  • The working life of LED bulbs can range from 10,000-50,000 or even more hours (depending on the source of the LEDs). LED offers longer life cycles when compared to conventional systems such as metal halide or UV.
  • LED units offer faster exposure times when using hybrid or pure photopolymer emulsions. Keep in mind, there are many variables that can impact times, but here are some times we have experienced in the field from customers using our units: 5-15 seconds when using pure photopolymer, 35-60 seconds with hybrids and some dual-cure or diazo emulsions.
  • LEDs allow you to expose halftones and fine line details with direct and uniform light. The correct LED system partnered with the correct exposure times allows you to capture halftones as well as fine line details.

Do your homework! It is always your best practice to check exposure times by using an exposure calculator or a step-wedge. When comparing LED units, look for units with an output of 405nm Because that will provide the optimum cure, latitude, durability, speed of exposure, and reclamation regardless of photopolymer, diazo, or dual cure emulsions. With the correct LED unit and correct exposure times you can improve many aspects of the screen making and exposure process related to systems with UV tubes, spot lamps, etc.

We hope this information is helpful. If you have any questions regarding your screen printing needs, please contact us.

A Few Facts In Screen Printing History You Should Know

Screen printing has been around for much longer than most people realize. Andy Warhol is often considered one of the most well-known users of the method, employing it to transfer his pop art images onto different media – canvas being one of his favorites. His affiliation with screen printing is definitely an important part of its history, but there are several others to know as well.

Song Dynasty: While we don’t know the name(s) of the person or people responsible, we do know that screen printing was created during The Song Dynasty (China, 960-1279 AD). It must’ve been a very time consuming process, and quite a bit more involved than how we do it today, but it was used to turn plain fabrics into fancier ones using various designs… just like we still do now!

Samuel Simon: A patent was issued to English chap Samuel Simon in 1907, and he is widely considered to be the first recipient of a patent related to screen printing. To make designs, he utilized silk and cotton stretched over frames made of wood, and stencils that were hand painted.

Rotary Multicolored Screen Printing Press: In 1960, this device was invented, and its job was to add designs and writing to clothing – more specifically, bowling shirts. That garment was the hottest item at that time and needed a logo and a team name. It wouldn’t be too long before t-shirts would take over the title (more on that in upcoming articles).

These are just a few events that are important to the industry – and there are so many more! In future newsletters, we’ll share more fun factoids and pertinent people in the history of screen printing, so stay tuned!

Something BIG is coming!
