  1. @R C-R we're probably talking about different things. The RIP produces the raster for the hardware, not an image type file. Think of it a writing the state of each of the printer's physical dots. A 1200x600dpi printer for eg makes a 1200x600dpi raster. Affinity rasterising an effect at 300ppi is another process altogether and can degrade final output quality.
  2. Usually there is an intermediary format, a page description, PostScript is a very advanced one for example, the lower end is something like PCL. Vector data can be within this. The print driver is technically the RIP, it interprets the page description and produces the final raster for the printer. What Affinity will sometimes (always?) do is pre-rasterise the document to pixel data, and send that in the page description to the RIP(driver). The RIP still has to interpret that to the actual output format of the printer hardware.
  3. Sorry, that was me getting confused. I wasn't at a computer to check how it was. Attached is a PDF made using the process I described, it has pure black (100%k only) text. Try printing that from Reader with the "Advanced" print settings as: That definitely works as a process for printing k-only. If you are still getting registration black then your print driver / driver settings must be the issue. k-only-x1.pdf
  4. You need to ensure there is no colour conversion taking place at all - your text colour has to be set using the CMYK sliders, and your export colour profile has to match the document. Uncheck "embed profile" as that can cause problems. I'd recommend a new CMYK document, set your text colour with CMYK sliders to 100%k and then export to the pdf x1 preset (make sure that "embed profile" is off). That pdf should then contain genuine single channel black. You have to print from something like Adobe Reader (which is free). Printing from Affinity is a non-starter.
  5. It is. That is the result of sending RGB "black" - it will print as a mix of all four CMYK channels and effectively cut the print resolution by around 1/4 compared to printing 100%k. In the export window, click more and show what is set in there.
  6. @efc You cannot print CMYK directly from Affinity. It will always go through an RGB conversion prior to getting to the printer. You can maintain correct separations on export to PDF, can you show your PDF export settings?
  7. I realise it's a different issue, but it may be related, below is a thread that contains a "white is yellow" monitor profile if anyone wants to see if indeed it gives the same issue in Adobe. I've not actually tried the profile in use, as I don't have any other colour managed apps installed.
  8. Part of the problem might be that the apps use a third-party colour management system (Little CMS). How much knowledge the team have of the internal workings of that system could play a part. I've looked with a profile inspector at a "yellow is white" profile from a user here and that profile didn't have any obvious issues. I don't have Adobe apps to test it with, but just that assertion the profile is faulty should be taken with a grain of salt until genuine proof is provided.
  9. Create two rectangles, one larger than the other.. Put the gradient on the large one and skew it. Now drag that layer to be "inside" the non skewed rectangle and it will clip it.
  10. "..specific display profiles that are installed by default for various displays. They are defective in regards to their compatibility with colour management solutions and do not work properly" I'm interested to see how you twist that to mean defective profiles can work properly with some colour management solutions. How about we hold Serif to task to explain their assertions instead of trying to twist words and deflect the question?
  11. I just had a read of this: https://affinityspotlight.com/article/display-colour-management-in-the-affinity-apps/ There's mention in there of another colour profile issue of white displaying as yellow. It's dismissed in a fluff of hand waving as a bad profile that affects all colour managed apps. Comically, they suggest searching for the phrase "whites are yellow" whilst that phrase a is link to Google searching for "Photoshop whites are yellow" - obviously don't want people coming across the Affinity complaints lol. Anyway, the article provides no detail of what a "bad profile" contains, and gives no proof at all that a profile that gives yellow in Affinity does the same in all other managed applications. All this is to say don't hold your breath for a detailed answer from Serif on this issue. P.S. I do really like Serif and Affinity, please don't take me off your Christmas list for this
  12. If / if not. Doesn't make any difference. I (and others here) have tried everything. Stirring my tea anti-clockwise looked promising for a bit, but no. Nothing at all whatsoever causes CMYK output from any Affinity app on any OS. There is no driver issue, no user error, no mis-configuration. It is simply hard-coded into the app to convert to RGB prior to handing off to the OS/driver.
  13. I share your pain - I took my first steps into the world of colour profile creation with an X-Rite spectrophotometer, a PostScript printer and Affinity. Yeah that didn't end well 🤣 On the plus side, I have plenty of "note taking" paper with pretty colour charts on the back
  14. Looks nice and clean, the house for some reason catches my eye when glancing at things - maybe because it has that third colour the others don't? On a usability side, is there a different function for the first green "+" to the second one? If so, maybe something to differentiate?
  15. I'm too tight to use Office, OpenOffice is somewhat stuck in the past, but it's available at the price I like Maybe a mockup within an app window would help to see how these look and feel in the real setting.
  16. How about going with a more simplified and unified palette? Eg. use the exact same gradient on the folder/clipboard/lock/star/bulb. Maybe make a silver handle on the magnifying glass and use that exactly the same on the bulb fitting/scissor blades. Pick one blue style for all those blue parts, make the floppy disk blue too. Also, change the notepad offset to match the clipboard/sheets of paper (they go right, it goes left). Feels like a little too much going on as it is. But then I'm a boring minimalist and I'd have it all in flat dark grey
  17. Sadly not, it's the same with Windows - you can have a PostScript driver cable of handling a pure CMYK data path but the app hands off RGB data at the first step. There was some initial confusion as the drivers are good at mapping RGB to corresponding CMYK primary (eg RGB of "pure cyan" would map to 100% cyan at the printer. If you want to dive into it (it's not a short read) the threads linked from the below post give all the details with a few of us testing on both Windows and Mac with PostScript printers).
  18. I'm going to go with the classic IT response and ask "have you tried turning it off and on again?"
  19. It's the same on both systems, there have been a few threads in the past of people testing on PostScript printers, the CMYK is never correctly handled. I still believe printing via a PDF and third part app (i.e. Reader) is the best approach.
  20. It's not so straightforward with images - there can be colour profile interactions between the document and the images that can inflate the size, if the profiles have to be included separately for example vs the whole document being in device CMYK. I'm not expert enough to fully explain it, I can point you in a general direction though - look into your image profiles and whether you are converting them on export.
  21. What is in the document? Is it just text / vectors or are there any images?
  22. Yes. Just pecking at things on my phone and couldn't remember the proper names
  23. It can depend a lot on your export settings and document content, but it's also influenced by there being three colour channels in RGB and four in CMYK.
  24. On the context toolbar, there is a button to make only straight lines. Turn that on, click once at your desired point, hold shift and then click where you want the line to end.
