I have created two PNG images with 0.4 opacity, which I want to print out on transparent plastic paper, purpose is to see lower sheet text and images show little bit clear from the above printed sheet.

So my question is that if it is possible to print out PNG transparent(0.4 opacity) image on transparent plastic sheet, which looks as transparent to see both the upper and lower image design on it ? And if yes, what printer required to complete this on plastic sheet ?

Something like this

I wasn't able to find out any particular answer on this, so please let me know if this is duplicate of any question or this is not a suitable question for this site.

  • Do you intend to have this printed at a professional shop or with a regular home/office printer?

1 Answer 1


For a specific answer there is some missing data in the question:

  1. the software used
  2. full color design or just one or two inks
  3. home or professional printing


Talking about the background, it doesn't need to be transparent to print over a transparent support. The white background in print means no ink (non printed area).

Talking about the design (printed area):

  • In printing the transparency is not the opacity, but percentage of ink density:

ink density

Higher density percentage = more opaque = the support is fully or largely covered with ink

Lower density percentage = more transparent = the support is partially covered with ink dots

enter image description here

The transparency is for effects on a file with other elements, but the result is a mix of inks.

Reducing the ink density decrease the diameter of printing dots, what in a transparent support allows to see through.


  • About the print file format, I don't think PNG will be the best. Here you have a full description:


  • Printing system, for a few labels today digital print do all types of supports and inks. If it's for a professional printing or large quantities, the most widely used printing systems for transparent support are flexography (cheaper and a little lower quality) and silkscreen printing.
  • I have created this with photoshop and i have used opacity, I may need to check ink density to create my image. Jun 4, 2018 at 11:52
  • @KirankumarDafda How many colors (inks)? I would recommend a vector program like Indesign, Illustrator, QuarkXpress, Word.

    ok, is a bit mor complicated. This is another question: how to get a semitransparent photographic image printed on a transparent support. The image on your question is a one ink logo.
