  • Printing in 4C vs 2C - HELP!

    Hi everyone,
    My factory (in china) is printing some test boxes. The package looks to be 2C. It's black and green (with white). There is a color lifestyle image that has a washed out green effect so it is also green. The factory has gone to print it and has indicated that the lifestyle image is 4C. They sent back a revised file to print as 2C and the lifestyle image is a completely different shade of green. I told them to print the original file but just print it as 2C. Any advice?

    See attached for reference.
    Thanks,
    JP

    Is this a design you sent to them? To print an image in 2 colors, it would have to be a duotone, or perhaps a grayscale image with a spot-color swatch applied in a page layout app. Judging by the saturation level of the original image, I'd say it is likely they were correct that it was not configured to print in 2 colors.
    I'd rather be killed than come to your party, but if you don't invite me, I'll kill myself.

      The image on the left is definitely 4-color. I can see it on my production monitor. It looks like a green tint was applied to a fairly light-valued full color image.

      When printing 2 color, you are printing with 2 spot inks.
      In your case, Black and Green.
      If you need a different green for the image from the green you are already printing elsewhere on the box, you need to specify a 3rd spot color.
      Or rework the file so the green is used in varying screen tints.

        Ok. The image on the left is a crop of what was sent. I agree now that I look up close that it is 4C. The one on the right is what the factory sent back to make it 2C. It is clearly an entirely different green which is not ok when you see the green across the entire package.
        1) Can I just tell someone to print a 4C color as 2C or does the file actually need reworking
        2) If it must be reworked... What is the more 'clear' way to change the image to 2C. Rework the green in varying tints or go grayscale with spot-color swatch?

        Thanks,

          The factory sent the attached file showing the revised images. THESE greens look the same. I know that colors look entirely different on monitors but I'm also dealing with China so feel I need to question everything. Would the initial pdf file look 'off' as per my original image but this one looks 'ok'? Should I re-do the file here or 'trust' that the green circle will be the correct green.

            Did you specify a Pantone? Or any other match system used for mixing ink for spot color printing?
            And a delta E you would accept on the color?
            And get a proof or drawdown?

            You cannot judge color on the monitor.
            If you redo the file, do you know how to set it up properly for 2 spot color printing? (if you are the one who created the original file...)

              This exercise of judging the green output on-screen is really of very little worth. We can answer your questions, but we're in no better position than you (worse, actually), to know whether the green will meet your expectations. Until you see the actual printed box, you can't be certain whether (you'll think) the green, printed on the box, is correct. We here reading your posts will never know, unless you tell us after the fact.

              There are a lot of variables, not the least of which are the color and finish of the box stock itself. Did you choose/specify the green ink, and if so, did you take the substrate color and finish into account, and did you use a matching system the printer in China also uses and understands? That's really all you can do.

                Ok, thanks. Yes, i have specified the pantone and yes, I have advised all printing, material & finish specs.
                Any additional feedback on these questions is appreciated:
                1) Can I just tell someone to print a 4C color as 2C or does the file actually need reworking? To answer your question: i am not familiar with 2 spot color printing.
                2) If it must be reworked... What is the more 'clear' way to change the image to 2C. Rework the green in varying tints or go grayscale with spot-color swatch?

                  1) No, the file has to actually output only the 2 colors.
                  2) You can apply your spot color swatch to a grayscale copy of the image, but personally, I always HATE the result when this is done. It very heavy-handedly applies the spot color based on white-in-the-image=100% spot color. It just about always comes out looking like a alien film negative, or worse if you ask me. The right way would be to make a duotone in Photoshop. This offers much more pleasant-looking results, and the opportunity to control the curve against which the spot color is applied.

                  All that said, I got the impression the "proofs" they were sending came from their conversion or rework to produce 2-color output.
                  I'd rather be killed than come to your party, but if you don't invite me, I'll kill myself.

                    Ok, thanks. Yes, this is their conversion... we're a bit rushed prioro to CNY. The good news is this is a proof so it's good to know duotone is a better option if it doesn't come out ok and we need to re-do it state side. Trying to make sure what I get isn't too off. Thanks!!

                      Hey all,

                      I searched for any article like this, however found none. I'm figuring that is because of the strange nature of this project.

                      I was approached by one of the parent's...
