Title: accu rip back ground noise
Post by: Kellan3737 on March 06, 2013, 12:01:40 AM
I'm trying to print two colour job on my epson 1430 with accu rip, and i'm getting a continous halftone dot the entire print.  does anyone have a suggestion to get rid of this.  I'm printing from photoshop and have had this issue before.  my photoshop knowledge is not very good. but I can stumble my way through it so any help would be greatly appreciated.

thanks!!

Printing out channels, correct? Use you Info Window, color picker, and check out the white/background. Anything not at 0% will print a halftone. 100% is pure black. You using Grayscale? Something slightly different maybe...

I ran into this a few times. You can print the file straight out of photoshop and get the artifacts then take the same file printed through Illustrator and they are gone. Never did figure it out. There was zero data where the dots would appear. Weirdest thing.

Grayscale, huh? Go to channels. Make a duplicate channel. Use your color picker and make sure your background is 0%. Print. You will be fine.

Make sure you have color correction set to none or photoshop in the print dialog. If you select printer it will do that.

Grayscale channel or spot channels,  a pixel is a pixel, but a dot, now that is a dot of a different color.
Sorry, wizard of oz flashback.

Like another mentioned, you have a 1% or more tone (all over your file). This happends during the mask and selection process ( or when scanned and not cleaned up enough in the background.

When caused by the masking and selections:fills process, it's due to filling with a black that is not 100% solid or not 100% white. Do not use the eye dropper to reference a black when filling, always hit the "D" key. That takes you back to default black and white and is always 100%....unless you've accidentally asigned a new default setting.

Copying a flat image with a black background from the RGB layers into channels is usually a culprit. When doing this, you must review you pasted black to confirm its 100% solid black or white.

Like the other guy said, use your eye dropper ( from the curves) window, command M...or control M ....and use the eye dropper on the right to refference the background. Click on the background with that eye dropper and is will clip out tha background %.

I am not familiar with what Purrre mentioned so that may be another issue.
