Hey guys, new to the forum and new to wide format printing. Basically we purchased an SC-500 to get into making signage and decals but am having no luck atm. The prints have gotten better since first using the machine but i still can't figure out what is wrong. Had a tech check the machine out and had the pump replaced and the capping station cleaned up which after a few head cleans brought the quality up a little but as you'll see in the attached images, the quality is still quite poor. Regarding the black, the tech said to run some prints through as the solvent in the ink may clear it up but it hasn't enough to make the printing noticibly better. There are visible lines through the 6 colour test print, and other than black, i cannot obtain a solid colour at all. I tried changing eps versions all the way down to version 3 and changing between postscript 2 and 3 for all to see if it was a file issue but no luck with that either. The images i printed were all saved as CMYK, no rasters used. The sunset way a tiff i found online to try someone elses file to further check if it was my file settings but came out the same. All prints were done with the SOL Gloss White profile at either super or photo (min 720dpi either way). Could it be a problem with colorchoice? Or am i looking at hardware issues? The tech has a new head that he'll install labour free at cost if the black doesn't clear up but i need to make some quality prints to make some money back before spending even more money lol. Any help would be great.
