Staff stokerg Posted September 8, 2019 Staff Share Posted September 8, 2019 Hi stutes, We can't convert a page to grayscale, you could convert the whole document. I guess one way would be to create a separate grayscale document, save it and then use File>Place to bring it into the main document. But when you Publish as PDF I don't how that would be treated.

walt.farrell Posted September 8, 2019 Share Posted September 8, 2019 You could apply adjustments to the page, such as an HSL layer to desaturate colors.

Given that the overall document is still color, won't the grayscale pages you insert into the color document also end up as color pages, albeit gray? How is that different from desaturating a color page, in the end? (If you can't tell, I find the concept of different color settings for different pages within a single color file confusing ) Quote -- Walt Designer, Photo, and Publisher V1 and V2 at latest retail and beta releases PC: Desktop: Windows 11 Pro, version 23H2, 64GB memory, AMD Ryzen 9 5900 12-Core @ 3.00 GHz, NVIDIA GeForce RTX 3090 Laptop: Windows 11 Pro, version 23H2, 32GB memory, Intel Core i7-10750H @ 2.60GHz, Intel UHD Graphics Comet Lake GT2 and NVIDIA GeForce RTX 3070 Laptop GPU. iPad: iPad Pro M1, 12.9": iPadOS 17.4.1, Apple Pencil 2, Magic Keyboard Mac: 2023 M2 MacBook Air 15", 16GB memory, macOS Sonoma 14.4.1 Link to comment Share on other sites More sharing options...

thomaso Posted September 8, 2019 Share Posted September 8, 2019 The Black & White adjustment generates K only output. For image resources you could use the "K only" button, which will convert RGB resources to grayscale in 4c and reduce CMYK resources to their K channel only. Another option would be to export the file or specific pages as grayscale PDF and combine the wanted pages of the resulting PDF with that which should have colors.

If inspected in pitstop/acrobat, it is indeed all on the black plate. walt.farrell 1 Quote Link to comment Share on other sites More sharing options...
stutes Posted September 9, 2019 Author Share Posted September 9, 2019 Thanks for all the suggestions everyone. I'll give them a try next time I need to print a document that has both color spreads and greyscale spreads (in the next couple of weeks). If you wondering why, it boils down to cost. Our in-house copier has a contract that charges more for color copies (to be expected). But when I print, I can set the driver for the color quality to "Auto", which detects if the pages/spreads have color on them or not, and if not, it prints in black and white... and in turn costs less. This even holds true for pages/spreads within the same print run. So, to keep costs down, I print the cover spread in color, and the rest of our booklet in black and white. My current workflow involves exporting to PDF and converting the inside spreads to greyscale using Acrobat Pro. And that works quite well. Just looking for non-Adobe options.

rjav Posted March 9, 2023 Share Posted March 9, 2023 I'm in the same position as Stutes and for the same reason -- cost of printing colour pages. I have made several attempts to export a greyscale PDF but the pages only look grey: they are, in fact, made up of CMYK. It should be simple, shouldn't it? Now, I have to go back and replace all the colour components with greyscale alternatives. Quote Link to comment Share on other sites More sharing options...

If your Affinity document has a different than the Gray colour space choose for export the Gray Space + an according profile, and activate the option "convert image colours spaces".

rjav Posted March 21, 2023 Share Posted March 21, 2023 Thomaso and others I have had time to carry out more tests and it seems to be as simple as I thought it would be The key is setting the ICC profile -- this was not an issue with InDesign but I had to make sure that I set up the Affinity document with the same profile that my printer was using (which was FOGRA39) To export a greyscale file I had previously chosen the "Gray" colour space but then used one of the five available grey ICC profiles When the printer opened the file, because it used a different profile, the grey-only PDF was converted to a CMYK mix which only looked grey The point being, as others have noted, that any CMY on the page means a higher printing cost This time, I chose the "Gray" colour space but used the document profile (ie, FOGRA39) and, as Thomaso has noted, selected "Convert image colour spaces" The printer has just emailed back "All black breakdown! No colour found" Now I will be able to produce a master document using original images which might be in colour for a PDF which is emailed to some subscribers (they might as well see it in colour) and then convert selected pages to grey only for the printed version Thank you to all who have taken an interest in this Quote Link to comment Share on other sites More sharing options...

This writes the profile as an "output intent" which automatically gets used when the PDF gets opened on a different computer.

rjav Posted June 8, 2023 Share Posted June 8, 2023 Just an update to this. I haven't tried Thomaso's suggestion of PDF/X but I have just sent off the June issue and had the same old problem. In checking my saved Settings for the grey-only output, I found that "Embed ICC profile" was ticked. When I unticked this, the grey pages were free of CMY. With this issue in production, I can now install V2 and see what happens. Quote Link to comment Share on other sites More sharing options...
