    Good day folks

    Print on optical clear – backed with 25% white or 50% white or 75% white?

    The client want to print on optical clear, want to show more colour, so we need to back with white but still have some transparency.

    I guess I’m looking into transparent white, in few different shades, any idea what route to go for?

    do you mean printing with white ink or overlay with a transparent white?

      My printer doesn’t print white. I was hoping to find 25% white to back with. No luck.

    what about frosted vinyl behind the printed clear?

      Did that. In my office looked good. In their office lighting was bad and they didn’t choose it.

    i think your trying to achieve the unachievable mate, same old case of the customer wanting too much. I think a double pass would help to deepen the colour

    Just out of curiosity, Do you charge extra for the likes of trial and error opacity testing or colour matching for customers that are very specific about the finish they require?
    If you don’t, you really should.
    I have a standard list of stocked coloured vinyl and the same with the likes of digital types of vinyl.
    If I have to order in something in particular and the volume doesn’t cover the likes of a 50m roll. then I charge them for it.
    I also do the same if they do want a particular shade/colour of vinyl that I do not hold. i.e. they need 3 metres of a certain colour, I tell them I need to buy it in increments of 10 metres and costs will be passed to them.
    I do the same if the output of a print isn’t the shade they require.
    i.e. I will run a print test to hit the colour they do want. but I charge them an hourly rate plus the media used to do so.
    these are all extras over and above the cost of the job.

    do not get me wrong, if the volume of work is plenty and I can easily hide the time involved in colour matching etc then I won’t even mention it, and lose the time in the overall price.

    Regarding the white ink being laid.
    I think if the print has to be transparent then 25% white.
    If colour depth, then 50%. But as above, if it’s so important to get colour shades and transparency correct. the more white you add the less transparency you get. So kind of goes against what you are trying to achieve?
    I guess it depends on the density of your white how it will look.

    Personally, if my customer was being pedantic about it. I would print the photo/graphics 3 times up the width of the roll.
    so if it’s a square image:
    * Print three photos 440mm
    * One backed with 25% white ink
    * One backed with 50% white ink
    * One backed with 50% white ink
    fit it to the glass and let them decide!

    As I said, I would charge them for this service.

      @admin Yes. I charge. I did 2 lots of prints at full price as an order. My printer doesn’t print white but even with the printer that does, as you also mention, when white is printer the transparency is gone.

      Sample is approved and is a standard procedure sample. Print on ultra clear. Thank you all.
