So i have a big sign job (CMYK)that i missed my window to have it done today because the black areas on the print comes out wavy & almost like a grey gradient, I performed a cleaning a few times did a test print looks fine, ink level is a 78. Is there a setting i might have changed? should i put a fresh black cartridge in?

also every other color it prints from greens, to blues, to pink- print fine


thanks in advance for any suggestions & help. I'm still in the learning curve

nozzle check comes out good, one this i noticed was it tells me it is missing the ICC file? I read up on what an icc file is and would guess that to be it but how to I go into to change or setup I cant find much info on it??

well, this is the best my iphone can do, the best way i describe it is semi wet paint and taking a broom across it leaving these white lines, yet only in the black ink areas.

I'm sorry if the pic sucks, thank you for all of you help.

also I think i got the icc thing fixed, but still prints a messed up black like the pic shows

artbot,

what did the following mean by 100% black, other than the obvious being a 100% where would I tone done the percent of black on a CMYK print?, here is the quote I'm talking about....

"i did that just this AM (thanks) and its a good measure of troubleshooting. My black looked messed up, my designer was trying to print pure black (100% k) and thats why it was coming out like that. I am gonna change the color of green b/c I think that color just sucks and we will see what happens.."

man you are asking the wrong guy... in my 14 years of digital printing i've never had to become more than a novice to print what i use printers for.... i'm assuming it was either discussing they designer was setting the ink load in the rip to 100% or using a rip setting i've seen called "pure black" (guess if it sees black, it will just blast black for that section of the file), or, probably not, going for a non-process black/grayscale black. meaning to not use any other ink but black to achieve the black tone, this would not allow for dithering in some lighter black areas.

tomorrow there will be some real rip gurus on here, of which i am not.

...no problem... my last 12 substrates were 12 different colors of white oak and ash veneer (gray brown stain to turquoise dye)... so i just eyeball it as i go. hope all is well and it gets figured out today. i'm out of town the rest of the day.

the black is almost to the point now to where i think its just my eyeballs and it would be fine to print but then i go look a the bike we wrapped last week and the black is perfect, im still waiting on sign warehouse to call me, but Ive been waiting 3 days also every time i call them, they say yup the tickets in, im really starting to be disappointed in the customer service with as much money i have spent with them
