  Why does white vector print a feint background?

  Posted by Peter Dee on 28 January 2013 at 15:28

  I’m doing some site board prints which have a lot of white background but the printer is laying down a very feint background on the white vinyl.
  I’ve tried the rectangle set at RGB 255/255/255 and also set to "invisible" but both the same.
  Printer is SP300 with Signlab 9.1 via VPM rip.
  Any ideas as it shouldn’t print anything at all for white!

  I’d put money on it being RGB that is the cause. Try changing the file to CMYK, and
  setting the background to white.

  had this after i created a profile and is a incorrectly set white point in the profile.
  also had a customers bit map file do this which was there programme saving the jpeg with a bum profile.

  Thanks for the feedback. Tried setting the vector to a cmyk colour but no change.
  I had altered the stock profile so tried the default setting – just the same.

  I have found a workaround by rendering the background to a monochrome bitmap. Absolutely perfect but not really the answer.
  Perhaps Signlab does not produce a pure white "colourless" swatch regardless of what it says.

  With Versaworks if you use the Max Impact rendering it will do what you are saying. Don’t know how Signlab works but could be a rendering setting
