Static is the excess or deficit of electrons on a material. Static in screen printing is most often caused by friction, separation, heat change, and improper grounding. Screen-printed products normally experience all of these during handling. Potential results of untreated static energy include ink spidering, sheets sticking together, delivery/stacking difficulty, accumulation of dirt and dust, electric shocks, damage and interference in electronic components, and even fires and explosions.
Dot gain is a challenge for garment screen printers, whether the job involves four-color process, simulated process, or index separations. Decorating textiles means working with surfaces that are 65-90% solid, which leaves a 10-35% chance of missing a printable surface.
One great way to elevate the level of detail and quality that a screen printer can handle is to look at reproducing fine-art designs onto garments. The challenge to re-creating fine artwork tends to relate to the fact that styles and media have to be simulated through some form of halftone to be printed onto the garment. An additional challenge to fine-art reproduction is that it may cost more time in hours and effort than most of the profitable work that comes in the door. Having a standard setup that can qualify the order up front can prevent headaches in production.
Happy 100th birthday, screenprinting!

Automotive designers are discovering that film insert molding (FIM) now offers much more than the usual dashboard interfaces. Led by the European market, FIM is enabling designers to achieve striking results all around the vehicle that add value, enhance the brand and, ultimately, boost sales.
The wide-format-digital market remains a growth business. Growth comes from two major sources: the conversion from analog to digital and expansion in digital-printing applications.
I recently picked up the guitar again after an 11-year break. Nothing serious, more like Willie and the Wheelchairs—just a group of guys getting together. In the old days, as a youngster, I used to wear out records, playing a part over and over again, lifting the needle arm and dropping it, writing down lyrics, chord progressions, or trying to work out a lick. Most everyone, from Elvis on, seems to have learned to play rock this way.
