Some of the prints I made with my new 4900 had small spots that didn't receive ink; I call them pinholes. They probably arose because of a spec of dust on the paper.
Of course, the first rule is to wipe the paper with a microfiber cloth before putting it in the printer, which I routinely do now.
Still, there is always a possibility of pinholes or other small defects occurring in the printing process. It would be a shame to just throw out the print if a quick fix is possible. My question is: does anyone know of an inexpensive and easy technique to touch up inkjet prints (or retouch, as referred to in the old days of darkroom photography)?
The process I contemplate would use a very fine brush with a mixture of inks/paints with solvent that approximates the color of the region surrounding the pinhole. It would be important for the added color to closely match the surface characteristics of the print.
I read somewhere that all one needs to do is save the ink from expended cartridges in small bottles. All well and good, but I haven't used up any of the 80-ml cartridges yet and it is likely to be a long time before I have a complete set of inks.
A "complete set" of inks probably consists of the one to three blacks and three primary colors (e.g., cyan, yellow, and magenta). Any comments on this?
So, my basic question is what types of inks or artists' paints could one use that would match the surface of an inkjet print made with glossy or rag papers, outside of the ones used by the printer?

This is not always an easy task but I would recommend a set of art quality felt tip markers that are archival and permanent. You can probably find these at your local hobby or art store.

I have used artist’s felt tip markers mentioned above and acrylic paints with a fine brush successfully.

It also helps to keep the printer covered with a clear plastic sheet when not in use. I usually cut a cover sheet from the plastic bag the printer is shipped in, and have never had a pinhole or ink dropout since I started doing it.
Epson papers are essentially dust free in my experience. I never wipe them, for fear of damaging the surface or introducing a dust mote.

I think I have found a solution to my problem.
I went to a local art supply store and asked for their advice. They told me to try using FW Artists' Acrylic Ink, made by Daler-Rowney. I bought a bottle of the black ink. This product is heavily pigmented; it is so dark that can be thinned with water but is water resistant after drying. I found it needs to be thinned at least 1:3; further thinning makes it even more manageable, but of course that depends on the color you are trying to match.
I have tested this on two papers: Epson Hot Press Natural (matte rag )and Red River Arctic Polar Gloss (gloss photo). It seems that both retain the same surface characteristics of inkjet prints made on them, which is one of the requirements. It is necessary to thin the ink quite a bit so it gets absorbed by the paper. These inks come in a variety of colors as well as white, making it possible to match the color on a print that needs touching up.
So acrylic ink, together with a very fine brush (e.g. size 0), seems to work for touching up small pinholes in an inkjet print.
