How to get Screenprint Positives From An Epson Printer
Epson printers have been used for production of screenprint separations for some time,they are cheap, well built, and have good feed mechanisms which give reliable registration. The first effective printer was the Stylus Pro 3000 model, a workhorse that can still make sure churning out separations after almost 10 years platform. In particular the 3000 was the right format at a reasonable selling. The separations are reasonable quality, chemical-free and give the screenprinter control over method. The Stylus Pro 3000 used a dye ink which is compatible quite a few clear films. Printing equal to 75lpi it has been a fine printer. This dye range was superceded by the 4000/7600/9600 series which use Ultrachrome pigment ink. Pigment ink is less compatible with films and this proved hard for screenprinters until the development of microporous films such as Agfa SelectJet. Epson's newer printers your Ultrachrome K3 printers 4800/7800/9800 and their close relatives 4880/7880/9880 and the 11800. Epson are aiming in the photography market and this ink was developed to correspond to the gloss of paper for photographic prints. Black and white areas on a print are covered in ink, neighbouring white areas are plain paper, in reflected light they appear different unlike a traditional photograph. The K3 ink is better matched for this application. Unfortunately it is less suited to producing screenprint separations as the Ultrachrome and dye ink types. Epson have introduced the 4400 and 4450 range aimed at the CAD market, together with a 'Film' version which use Ultrachrome ink and these types of effective for the screenprint market but there are many Ultrachrome K3 printers that have been bought for proofing or display that could be pressed into service as imagesetters. The problem whilst X800 printers (X800 here means the 4800/7800/9800/4880/7880/9880/11800 etc.) is the ink volume that do produce is not a convenient size, the mask is either too weak and allows some light through or overweight and fills in details. Colourgate tackled this issue by adding a proportion of yellow ink to black friday 2010. Yellow has the next highest uv density of the inks. This doesn't look very pretty twenty five years widely adopted. Wasatch have produced a much more elegant and practical solution - Epson heads are able to produce a range of dots for different resolutions. A 1440dpi x 1440dpi resolution has four times as many dots as a 720dpi x 720dpi, to own correct colour it is necessary for the droplet volume to be four times as great. Wasatch have harnessed this to print different droplet sizes next to each other in the same line, (variable dot size). This the ink level to be adjusted to the optimum coverage without additions and allows this impressive connected with inkjet printers in order to more versatile. This variable dot option available in the Wasatch SoftRIP SP version. This is another module to the base version. Wasatch SoftRIP will be the industry leader for screenprint separations and with this array of features for the screenprinter it difficult to see then why.
