  1. I've used this feature since 2005 as far as I remember. Quite sure. So it must have been CS2 or CS3
  2. It's not multiplied. It's overprint and it works in one single run on a UV direct to plate printer. The spot color which is set to overprint here is assigned to the white color in the RIP and is printed underneath first although it's above here. But again in one single print run. And with the extra channel you can do things like printing white just under particular parts or print only 30% white etc. Karte_Druck_600perc_weiss_unterdruckt_BD_X3.pdf
  3. @thomaso don't know what happened but here again. Skull5.pdf Skull5b.pdf
  4. wow. thank you for lining out more useful cases for 1-bit-tif than I expected first.
  5. Because some features are not only specific to AF Publisher but to the full range and collide at that point in AF Publisher where you try to use features which have to be implemented in AF Photo.
  6. Actually, it's a bit off topic after all, because our problem of not being able to save 1-bit-tif-files in the first place doesn't let us create images which could be used in this very practical way.
  7. What's this feature and where do I find it? Can you have both channels in one pdf file together? the grey rectangle symbolizes a physical piece of metal for example. It's just for checking the final look in this case. Not really necessary for the print file here. But it shows the problem, that if you want to put just the 1-bit-information on top of your artwork to mark the white print areas it doesn't work. The spot color channel for white needs to be set to overprint to be put together with your artwork into one single file. I tried to mimic that with the multiply option. But it doesn't obviously work. I attached two pdf files. Skull 5b would be the final print document. Maybe it's easier to understand if you think in terms of glossy coating on particular parts of an image. You would put a spot color channel like in Skull5.pdf on top of all and set it to overprint. How would you do that with AF Publisher and finally have one single PDF with all spot color channels and CMYK together? Skull5.pdf Skull5b.pdf
  8. Yes, that seems to be the problem. So when 8-bit is used, white is white not zero. To use multiply doesn't work because then the spot color get's lost since of transparency flattening
  9. Well, in Publisher it works partly. Would be useable, if the white inside the bitmap had zero information. Or if objects could be set to overprint not just colors. Imagine you had a dark object and you want to print a lighter color on it. You need to underprint white first. Usually, you put an extra spot channel into the pdf which you set to overprint. This channel is printed white. And then you can print another color on it. First picture AF Publisher, second InDesign Additionally, the final pdf file size is far too big.
  10. - I request - to be able to create 1-Bit tif files with either AF Photo or AF Designer. - white needs to be zero instead of white color
  11. I need 1-Bit support for flatbed direct to plate UV-print and for Riso printing. Our layouts for the direct to plate print use complex white underprint which is set up via spot color. Currently we generate 1-Bit tif-files which get assigned with spot colors in InDesign. Same with the Riso print. Color separation for spot colors is a lot easier with colorized 1-Bit files.
