Trying to print a very small design (smallest side is 0.035 millimeters). The accuracy is very important, even though this is not readable by normally sighted person's naked eyes. Tried printing on 2400 dpi laser printer as well as LED photo printer on photo paper. But they don't turn out clear, if not just a blob.

    I'm voting to close this question as off-topic because it is a question about printing a microscopic design, not about photography. – mattdm Nov 28 '18 at 2:13
  • I'm having a hard time imagining practical, existing photographic applications of your problem, without getting into semiconductor mask printing (microlithography) or the like. But I'll bite: what is the resolution of your design? I.e., how many pixels is your image/design? – scottbb Nov 28 '18 at 2:23

    well... it's almost on topic. take a photo using the film camera, develop the film, and you will get the miniaturized version "printed" on the film. – szulat Nov 28 '18 at 3:29

    (to explain: at about 0.7 micrometers, your stuff is smaller than visible light, and you'll deal with effects of interest to holographers, not photographers....) – rackandboneman Nov 29 '18 at 13:33

The printing process for the finest printed detail is gravure on non-porous stock such as plastic generally speaking. It's the way currency is printed among other valuable types of documents.

I have also make calibration combs for radio telescopes photographically using process cameras (achromatic lenses) to place images on sound-recording film which is quite fine-grained and can render detail well. Sound recording film also has excellent opacity at dmax.

For ink-jet accuracy, you must find the finest dot-addressability (as in a fine line screen) not only the spot size (per scan) or the dot size of the ink jet orifice.

Image edges on paper or film aren't sharp and smear or "spread" due to photographic image "fog" or printed ink "dot gain". The smaller the image, the greater percentage of it is affected and degraded by unwanted image "artifacts."
