Greetings, I am new here and I am here because I believe you guys can give me some decent advice. I live in Slovakia and we have photolab where we decided to have dye sublimation as minor bussiness. Now, we have 2 printers Epson D88 and 1400. We have third Epson 1400 in a row, because we always had problems with it. First we used Grawerton inks (made in Poland) but we still have problems like no printing of black color, blue color and so on. We have changed it to Artainium inks and whole new 1400 but results arent good aswell. Well, results were nice, but after few months (maybe 3) it started to print red color on greyscale. I have red shadows on portrait and so on. That Epson D88 runs still on Grawerton ones and performs nice. But we need 1400 for A3 puzzles. We have small shop (40 sq meters or so) and there is 26-30 degrees celsius of heat 365 days a year and 19 inch CRT monitor is just next to the printer. Can it have any bad influence on printer ? Should we change printer or inks ? please help ... thanks in advance
