HELP! Urgent help drying ink
I’m off tomorrow for a family funeral, and came in to an order for 10 A0 posters, which they need for tomorrow. It’s not a problem except they’ve all got a solid black background, and I just cannot get the ink to dry!
I am using trisolv 200gsm paper, using the right profile, genuine inks, heaters are on full heat…
I just cannot get the things to dry out though! 😮

Try something like a standard vinyl profile as I find these put down less ink, I use oracal 3164 on high quality. Heaters on 40 and 45 (45 on dryer side)
Did a large (1500mm x 1300mm) black poster the other week and left it printing on its own overnight onto takeup and was fine.

Just trying the MD-5 Profile as that’s usually pretty good.
Need to call out and pick another ink cartridge up too 😳

I would check the profile, and see how the black is made up. I find that a rich black
made up as following works well on our Mimakis, providing the profile doesn’t change
the balance.C = 25% / M = 25% / Y = 25% / K = 100%.
Not sure on a Roland, but you may have to set your RIP to honour primary colours,
or words to that effect. We use the same paper as you, and find that this dries fine
by the time the print has got to the take-up. -
There’s a preserve primary colours option on there…
They seem to be drying a little quicker using the MD5 profile… going to run out a few more now.

Do you have the facility in your RIP to sample a colour using the eyedropper tool? This
should tell you the composition of your black. If the ink limits are too high, maybe you
could alter them to something like the rich black I use. If it’s an EPS, AI, or PDF file,
I would do this in Illustrator. If if it’s a JPG, I would do it in Photoshop using the magic
wand to select all the black parts. There is also a facility in Onyx (our RIP), to do colour
replacements, which is a very easy way to tweak colours on the fly – there may be
something similar in your RIP. -
Done a check in Illustrator, it’s something like 100, 25, 25, so not excessive.
I’ve got them coming off the machine dry enough to handle, just having trouble with them catching the take up bar, and scratching the ink. 😳
Doing some machine minding now.

OK posters printed, deliver them tomorrow.
I’m not overly happy with the print quality. Customer understands that time was against us.
Think I need to calibrate the printer, do the bi-directional alignment, give it a good clean and new wipers.
