Screen’s B2 Inkjet Press, the TruePress JetSX achieves key industry milestone

Posted on by Dave Erlandson | No Comments »

I recently attended Screen’s media day at their showroom in Rolling Meadows, IL.  Four presses were prominently on display and running.  They were showing two presses for the commercial, mailing and transactional document markets: the B2 inkjet press called the TruePress JetSX and the high speed roll-fed TruePress Jet520. Also on display was their new UV inkjet label press called the TPJ-L350UV and their new wide format press the Screen TruePress Jet W3200UV

The Screen TruePress JetSX was first announced at drupa 2008 and shown again at drupa 2012.  There are now a handful of installations throughout the world. The first US installation is at Foremost Communications in Grand Rapids (MI).  According to product manager, Aron Allenson, the press is designed for shops that have a print volume of 800K to 1 million letter size impressions per month and is extremely reliable, typically running for several months between service calls. The JetSX’s true value is its ability to run light weight stocks through 24pt board.  

The press uses piezo inkjet and uses aqueous pigmented inks. The cost per page varies with coverage as there is no click charge, it’s pay as you go, but a typical average is 2 ½ cents per page. Aron’s cost comparison with offset showed the breakeven point at approximately 5000 sheets.

When I was there the press ran both simplex and duplex jobs with a variety of images. The image quality (1440×1440 dpi) was terrific and the paper being used was standard, coated offset paper – a key milestone for inkjet in the commercial market. The JetSX prints on coated and uncoated cut sheets, including any gloss or matte standard stock, with no need for a precoating stage. A postcoat unit applies a spot coat to protect image areas. An infrared drying unit dries the sheets before delivery, allowing sheets to go immediately to postpress.

Being able to print on standard coated paper stocks at high quality (offset-like) in a production environment is a key milestone for the inkjet industry because it is a fundamental requirement of the commercial printing industry.  While there is a market for output on uncoated paper, the image quality requirements for a large percentage of the graphics arts market requires printing on coated stocks.  And while many inkjet presses can print on coated paper, they often use special inkjet paper, which comes with a significant upcharge. It’s great to see an inkjet press deliver high quality output on standard cost, coated papers.
