Hi all, 

The final print for my design in Affinity publisher is just not looking great.  I won't at all be surprised if there is some user error here, but I've done a ton of debugging, and I'm hoping you might have some insight. I have a really expensive printer that prints 1200 dpi, so I'd hope to get a clean print (and I get crisper prints from Word document exports).  I'm also needing to use smaller fonts, so crispness is really important.  

Summary of the main issues: 

  1. There is a lack of crispness to my printed text. Grainy/hazy
  2. Black text on top of color has almost a white haze around it

Setup summary:

  1. $6000 office printer, Sharp MX 3640N with correctly installed driver.  I also ran registration adjustment and color calibration adjustments on the printer, to try and 'align' the CMYK printed dots
  2. When printing, I select, 'fine' for print mode', and 'very sharp', for sharpness in the print dialogue 

Attachment summary: 

  1. AFPUB design file (scrubbed of personal/firm identifiers)
  2. PDF Export of design (using the PDF/X4 presets)
  3. 600 dpi scan of the printed result while using 'colorimetric' in print dialogue (with annotations showing problem areas)
  4. 600 dpi scan of the printed result while using 'standard' image type in print dialogue
  5. Screenshots from print dialogue 
  6. 600 dpi scan of a printed page from a word document exported to PDF. 

Comments

  1. The text in the table is set up as a 'global' black, with CMY=0, K=100, with both spot and overprint.  Same with the disclosure sentence on the bottom.  However, I'm still seeing yellow in the printed output, so somehow in either the PDF export, or sending to the printer, this color has been changed. 
  2. When printing with the 'standard' image type, the colors are just not right. and my blues end up being too light. Also, the white haze behind the printed table text is worse. 
  3. When printing 'colorimetric' image type, the colors are closer to my design.   Both scans show the 'yellow' in text that should have zero CMY, and only K. 
  4. I'm working in the CMYK color space, exporting PDF-X4, but it seems something is messing up with the CMYK defined values.
  5. I tried using similar font size in a word document, exporting to PDF, and printing with the exact same settings.  It looks much more crisp, and no yellow. 

Any advice??  Any other things that might help you give advice or debug?? 

Thanks in advance.

I'll preface this with saying I've not used a Mac, so bear that in mind...

1) The first of your print dialogue screens has "pure black print" with the slider one notch towards "color". Does setting it "black only" have an effect?

2),3),4) Does your print driver have colour profile presets? All you are changing is the method by which the profile is applied, you probably need to change the actual profile to see any useful difference. In an ideal world you would create a profile for your printer/paper combination but that requires extra hardware. Start by seeing if your print driver has other profiles available. If not, you can print from Publisher and set profiles from there (Maybe, you can on Windows).

For the point about the white gaps around the black text on coloured background, look for "trapping" in your print driver. Setting that on should address that issue.

Hope that is of some help.

Thank you, I will take a look at these, I do see a 'trapping' option.

The text in the table part is K100 and it overprints so the yellowishness and knockout artifacts (halos) seem to be resulting from the printing environment (appearing that whatever you have in your PDF will get converted to RGB when sent to the printer).  I do not know the capabilities of Preview but I'd try Adobe Acrobat Pro or something similar that should be able to send printer data in CMYK. 

Thanks. I'll mess around with the Adobe Acrobat Reader free version first to see if there's anything in there... I'd love to not need an adobe creative cloud subscription (but if all else fails I can certainly load a trial and experiment).

The upper part has black in four-color CMYK, is there any specific reason for that, as that will certainly result in less crisp output. 

For the black color, I was mainly debugging with the table text and disclosure sentence at the bottom, since it was small font/italics and most sensitive to the issue. 

That brings up a question though... my understanding of 'black' colors is that layering CMY within the K will result in a deeper/richer black, and that K100 black alone is more pale.  Perhaps when printing font size 8, it's better to just use the K100 because any slight offset in the inks will result in those artifacts/fuzziness...  Is this just a tradeoff when doing non-commercial printing?  Sacrificing the richness of the blacks in order to have sharp output?  Is that just all dependent on the printer capability and calibration?   Should I make sure all of my blacks are K100 with overprint?

I've found the difference in "blackness" with my toner based printer is pretty negligible. You might find there's some way you can adjust how much toner it will lay down if you are getting a pale black coming out. You will get significantly crisper text with k-only as it avoids any mis-registration and you get the full 1200dpi dedicated to that one channel.

Did you try that "pure black print" slider all the way to the left? I get the feeling that is the equivalent of the "treat black as k only" setting on my Oki which is very good at doing what it says - it even converts registration black over.

Are those two print screens the only driver options you have or is there a dedicated interface for setting up the driver?

As a side note, I found that Illustrator provided a nicer output to Designer (I don't use Publisher) and it has more control for high end printers (e.g. you can set the line screen etc.). Weighed up against the price of the subscription though I didn't find it worth the cost - it's such a small improvement you really have to be looking critically at the documents side by side to see it.

But the main issue I think is whether you actually can output to your printer according to data you have in your PDF. Now it seems that you cannot, as colers get converted.

Agreed, this is certainly what I'm trying to nail down first.

Not yet unfortunately... I've been working from home, but I'll be stopping by the office this evening and will give that a shot.... I'm certainly hopeful for it, as well as your 'Trapping' suggestion

No dedicated interface for setting up the driver, only a 'printer features' section that is added when installing the driver. Under 'Printer Features', there is only one thing related to color, referencing a 'RIP style' choice between RGB and CMYK (default was set to CMYK so I left it alone).  I'm not sure what this is, there is also a checkbox there for 'no offset' 

There is one other Color section (adding screenshot), which chooses between ColorSync, or In Printer.

There doesn't seem to be a lot of options for you to play with there, one thing I would suggest though is setting the "Color Matching" to "In printer" - unless you really know what you are doing with colour profiles you will almost certainly get a better output from using the printer's in built profiles.

I'd also see if you can find the printer manual, as there's likely to be a few options for the colour handling through the printer. It *might* even have a way to calibrate the colours using the built in scanner to read it's own print output (I'm not sure if this will be the case, some very high end Xerox machines have this). In any case, there should be some form of in-printer colour settings for you to access and try (e.g. on my Oki there's a quick setting for charts/graphs, one for general office documents etc - they are just shortcuts to different colour profiles and rendering intents).
