NolaT Posted June 28, 2020 Share Posted June 28, 2020 Hello. To start, let me say that I am a total novice, so please excuse my terminology. I am just beginning to learn Affinity Designer, and I have created an all-black vector image to be used as a film positive. However, I can't seem to get enough ink for an opaque image on my transparencies. I am still able to see through my image when held up to a light or window, which will not work when exposing. I have printed opaque black with this printer before using pdf files downloaded from the web, but the settings I use in Affinity Designer don't seem to be working for that purpose. I've tried exporting to PDF for print, using cmyk in both the template and print settings, 300dpi. I have tried playing around with a few of these settings, but the end result is the same. I have the cmyk settings all turned up to 100. Can someone please explain the best settings for getting the darkest black possible within Affinity Designer?

thomaso Posted June 28, 2020 Share Posted June 28, 2020 Hi NolaT, Welcome to the Affinity forums! I am not sure whether I understood your description exactly but it seems to want to print with your inkjet printer on transparent foil with max. black? If yes, the color space does not matter, just assign a maximum black set in the Colours Panel in any color model. So your CMYK file with 100c 100m 100y 100k should work to produce a very rich black, while 400% is even a bit much ink I guess. Could you upload a sample Affinity document and your trial PDF? Possibly also an PDF which had worked before as wanted? What app did you use to print your web pdf successfully? What kind of print medium did you select in the printer options in both cases?

firstdefence Posted June 29, 2020 Share Posted June 29, 2020 Inkjet printer software do their own conversion to CMYK don’t they? so having a document in RGB to get a punchy black might be an option and let the printer convert to CMYK. Have you printed to the right side… it happens lol! Have you tried different brand transparencies sheets Different Inks What printer are you using Maybe create a test strip sheet and modify the strips with different blacks.

That is the best advice. In which way? Isn't the goal to print a black as dark as possible – not to achieve a specific tint of black. I wonder whether the Affinity-internal print procedure might cause the unexpected result here, in particular because of this two experiences: 18 hours ago, NolaT said: I have printed opaque black with this printer before using pdf files (...), but the settings I use in Affinity Designer don't seem to be working For instance if Affinity does not send CMYK data to a printer but converts them to RGB before then a 4x 100% color will get prevented from reaching the printer but gets limited to a max of 300% as total ink coverage.

wonderings Posted June 29, 2020 Share Posted June 29, 2020 I would also check that when creating your document that the mode is CMYK and not RGB. You can select CMYK for output but people have had issues with that and do not get 100% K because the document colour mode is still RGB. If the printer is RGB you could try this makeup for the black - 0% R 25%G 25%B Quote Link to comment Share on other sites More sharing options...
Fixx Posted June 30, 2020 Share Posted June 30, 2020 It is also possible this specific printer cannot produce high density output. I have heard stories people printing to film with a laser printer have run the same film several times through the printer to achieve enough density. (Imagine that does not improve sharpness...)

Yes - but surely Affinity should support printing CMYK - this is ridiculous that applications marketed as pro apps don't support pro standards - I'm stuck with Acrobat 9 which just works for sending separations or CMYK composites - this is a taken for granted, basic requirement !?!?!?!?

NolaT Posted July 5, 2020 Author Share Posted July 5, 2020 Hello, everyone and thank you for responding. Apologies, but I have been working more than I'd like to and have not had time to revisit this. A bit more detail on my setup: I exported me original artwork as a PDF, and used preview for mac to print. I have also tried printing directly from affinity, but the end results look identical. However, I was able to print the file attached below in an opaque black--also using preview for mac. I used it to test my DIY exposure unit, and the transparency worked perfectly. When I created my document, it was set to cmyk and the color space is also cmyk when I export(I honestly am not sure what all of this means). The printer I use is a Canon IX6820(may be a different model number in Europe). Again, thanks to all for responding. I am going to try to create a test strip to see if I can find an appropriate black. vector-exposure-calculator.pdf Quote Link to comment Share on other sites More sharing options...
thomaso Posted July 5, 2020 Share Posted July 5, 2020 Some elements in your PDF seem to be grayscale and print in max. 100 K. Since you print from preview.app I assume you don't have Acrobat installed, so to check the color values in your PDF you might like to use this online tool https://www.pdftron.com/webviewer/demo/color-separation/ Un-Tick the Black in the left column to see those parts disappear, which will print in black only and therefore might not be as dark as wanted. In this screenshot those parts are marked yellowish. Quote macOS 10.14.6 | MacBookPro Retina 15" | Eizo 27" | Affinity V1 Link to comment Share on other sites More sharing options...

Dazmondo77 Posted July 6, 2020 Share Posted July 6, 2020 2 hours ago, Lagarto said: For full control of color, a CMYK end to end print procedure would be needed, but this is not supported by Affinity apps, nor is it supported by your printer! In such environment, it is possible that CMYK input with registration black (C100 M100 Y100 K100) produces K100 output, and gray or RGB black input produces four-color black output, and what you get is typically printer-driver specific, so unless the printer driver allows proper control, it is often a trial and error process to get the desired output. Madness! - when I started in the industry everything seemed so simple regarding printing or outputting to an imagesetter or proofer - my first home epson Stylus 800 colour printer just worked with a proper CMYK colour driver (at least on the mac) and all graphic design apps sent CMYK as standard - setting up for screen print is still easy peasy, as spots, but as Affinity users, the only option we have (at the moment) if we want to proof separations is Acrobat pro (I use 9) and a postscript printer or RIP, where in acrobat pros print dialog, advanced takes you to options for sending separations - so I'm guessing for your printer, you would need RIP software in order to simplify the procedure, or you would need to invest in an SRA3 capable PS laser printer that supports transparencies, which will be pricey. Note that Preview doesn't support printing true CMYK --- ridiculous that most software that can handle CMYK needs to convert to RGB and convert back to CMYK with a colour profile to simulate output intent and completely bugger up all your colours ------- inkjet printers print with CMYK inks ----- SO WHY CANT WE PRINT CMYK All pro graphics/DTP software supports printing CMYK to ps printers ---- apart from Affinity?!?!?!?!?!!?

R C-R Posted July 6, 2020 Share Posted July 6, 2020 3 hours ago, Lagarto said: As many photo printers support more than four inks ... Even many old budget 'all in one' inkjet printers have five ink cartridges, the four CMYK ones used for color & the extra (often larger) black one used for B&W printing. I think the idea is that the K ink is formulated to mix better with the CMY ones & the black one has a more opaque formula, or something like that.
