Hi george have you tried printing the black in rgb and not cmyk

Used to use a cadet with the Roland ColorRIP software. There is an option on the RIP for ‘special colours’.

Try that and you can select your black and convert it in the RIP to 100% black with nothing else. Save that new profile under another name to use again another time.

Same used to work with any other colours, we found it very useful when trying to match specific customer colours.

On the grand format machines here which generally print lower-res than Cadets etc. all areas of black are done as process black (100% everything) to give depth to the colour, otherwise printing a 100% black does give that dark grey effect.

some times i add 30 % cyan and 15% mag to the black this may help but the type of material is not helping.

quote George Elsmore:

Is it possible to print black on a cadet just using the black cartridge? using corel 11 and ripping in roland colourip? I have picked 100% K for the black but it still seems to mix inks….weird!!!

Yes, it’s easy to sort. Open your job in ColoRIP as normal, hover the mouse over any "black" area, right click and then select the "replace spot colours" option. this will open a dialogue box which will show you your current source colour (C0 M0 Y0 K255). Obviously this suggests it is already correct so what do you do? Above these numbers is a little radio button called "device bypass" check this and then OK your way out. As mentioned elsewhere, when prompted, change the name of your profile by adding some reference to pure black on the end of the original name.

Don’t panic if your displayed image no longer shows black but instead shows red stripes on everything that should be black. This is correct, it is just warning you that this colour is no longer being corrected – it will indeed print with just the black ink.

If your numbers are different from those above, you either did not select a pure black in Corel or you have colour management turned on in Corel and it is changing the values when you export the image as an EPS file.

OK?

I just make sure CMYK are all 100% for all black parts in the original file to make pure black. Works for me.

Presumably the same will apply to printing on the SP300 from Roland ColoRip? I do a lot of logos for a transport company printed on reflective vinyl. The logo is an oval 1000 x 600mm, black, with yellow text. Black is about 85% coverage. I always run outta C, M,Y, never K. Did a quick count of empty cartrages I started collecting a while age(to give me a better idea of order quantities): 8M , 7Y , 5C, 0K ! (K is now almost empty)
And, I have gone to 440ml ECO MAX cartrages on all colours a while back, K is still an old 220ml pre-max. And I’ve got more 220ml K in stock!! Will print ’em into the grave now, however! Thanks!!

Hi all, This is my very first post. 🙂
I had the same problem with my cadet, when i wanted to print just 100% Cyan Black etc, i found that it would always print in C,M,Y,K.
If you have Troop Version 4. go to job property’s and go to the 3rd tab, look for "perform color correction" turn that off, that should enable you to print single spot colors i.e. yellow cyan black etc also the quality of prints seems to improve quite alot.
You may notice that when u have unselected this option (color correction) the cadet will not plot, so go down to "use color mapping" on the same menu, and turn that off too, the plotter should now work.

Hope this helps
Lee 😀
