can anyone help with pdf & poor print quality?
I’ve got 500 shelf edge strips to print for a good customer of mine. Previously they had them done by a larger local printer & their customer rejected the print because of image qualith.
It looked to me like pooling of the ink, and printed a sample @ high quality for my customer, which has been accepted… Just means 10hr machine time to print them rather than about5 on standard.
I was planning on leaving it running overnight but now I am having problems with print qualith.
Its simply a grey logo repeated on a white background. The grey is however made up of 4 colours.
They’ve supplied a pdf with 21 strips & crop marks, but I don’t seem to get a clean crisp edge to the text or logo, as if it has been rasterised.I’ve done a feed calibration, bi-dir and a medium clean, but still can’t get it neat the proof quality.
I’m running an RS 640 using genuine inks.

open the pdf in your design software & see if the file is a bitmap then open your proof file & see what that is. May be it wasn’t the other printer at fault but the artworkKev

I’ve opened the PDF up in illustrator it is a vector logo.
Colour mix for the grey is:
C 10.98 M 1.18 Y 0 K 63.92
The logo isn’t coming out a solid colour, but you can see it’s made of several colours.
Attached is the logo, which is repeated along the length of the strips.

why can’t you print the original you supplied as a sample ?? forget the new file.

I am…
They supplied the files, I am using exactly the same settings, but it’s still not a perfect grey.
I am using the Tri-Solv 200gsm profile, on High Quality (taking ages) the same as the proof I supplied but it’s not quite the same quality. It’s not a smooth grey
Only thing that’s changed is I have used a new roll of paper, and done a feed calibration and bi-directional calibration on the printer.

Just a shot in the dark, can you not amend the colour so its made up just as a percentage of black? Then (I use versaworks) just use "density control only" so its only laying down black ink?

I think the customer is expecting it ‘their’ colour.
I’ve got it to a reasonable quality, but I shouldn’t have to wait 30mins to print 21 strips on high quality:o
Standard Speed should be sufficient which is down to about 14mins for 21, but it’s not.
Out of interest where is the ‘density control only’ option and what does it do??? 🙄
-
I believe it forces the Versacamm to only use black ink to produce greys and greyscale rather than using all 4 colours. My thinking was that if its only using 1 colour it might be less "fuzzy" where it lays each one down?
Long shot…….

I’m using a the Versa Art RS-640… don’t know if that’s an option in VW.
I’ve not seen it, that I can recall but don’t really go digging around in it often.

Its under the "Quality" tab, "Colour Management" in the "Preset" dropdown.
It’s probably on "Pre-press US" as default, change it to "Density Control Only", whilst you’re there try a job on "max impact" its the only one I use now!

Just had a look now.
I will run a set out using the ‘density control only setting’ and if that doesn’t work I will try MAX impact.
Mines set by default to Pre-Press Europe.
Thanks for the help I will keep you posted
