  • Printing a decent CMYK blue.. help!!

    Posted by Hugh Potter on February 13, 2017 at 4:56 pm

    Hi all,
    Can anyone help me out with the CMYK for a nice royal blue, looking for an equivelent to RGB 0 0 255 if possible… having a bit of a ‘mare trying to print one for the morning, everything seems overly purpley or washed out!

    thanks,
    Hugh

    Have you recently changed inksets? What inks are you using?

    Hi Phil,
    Still on genuine HP inks, nothing has such has changed but i’ve always struggled to get the right blue, more in the case of customers who for years have had a good royal blue in cut vinyl, I now need to find a close match in print for updated logo’s etc, similar to the oracle 551/651-057 traffic blue :puppyeyes:

    Can you not print a CMYK wall chart from the RIP?

    I know Signlab VPM & Roland Versa Works does. Its handy when trying to match colours.

    That’s a good question, I’m running RipCentre 11, I’ll take a look!

    Using the suggestion above of the 100/80/0/30 I have made a load of custom blues around that, just printing them now so I’ve some kind of reference.

    Glad I’m not the only one that has trouble with colour reproduction 😆

    I would be using around 100/95/7/14 but I have a solvent machine rather than a latex.

    Crank your print resolution all the way up!!!

    I have found blues, greens, burgundies and greys print a whole lot better when you are up to 1440×720 or more.
    Due to a lower dot count on the lower resolutions these colours don’t physically blend well.
