INKS - Recomendations for Specific Materials & Application Notes

A-A-208D - (Also TT-I-1795A) We have 3 inks that meet this specification: #42M, #141 and #1250

Aircraft Parts - A lot of people use #1250, which meets A-A-208D. However, some types of clear coat will dissolve the impression, so if the spec is open, we recommend #6459, a one part epoxy with excellent adhesion to metals and solvent resistance to such things as kerosene and hydraulic fluid. If you have to meet A-A-56032D, then you’ll have to use #6050 two part epoxy ink.

Aluminum - #1250 is the most popular ink. It also meets A-A-208D. #141 also works well if you need a slower drying time. #6606 is the best, but dries quickly on the pad.
FOR SELF-INKERS: 141 works well or you can use Ultifast multi-surface ink in a pre-ink stamp.

Brass - #628 works well.

Cardboard - Ordinary stamp pad ink usually works, but if you get feathering, switch to #532 indelible ink.
SELF-INKERS: Standard self inkers and pre-ink stamps usually work well. For glossy printed surfaces, use Quick-Dry ink in self-inkers or Ultifast multi-surface ink in pre-inks.

Cellophane - #445 Super Marking ink works well as do the #620/#628 plastic marking inks.

Ceramics - for glazed ceramics, we recommend #6459, for unglazed, the #532 indelible.

Circuit Boards - #432 is generally considered the ink to use on circuit boards as it can take a wide variety of organic solvent baths, and is non-conductive. This ink is aggressive and it requires a metal or special pad, so if your impression is not going through a solvent bath, then the less aggressive #476 may be suitable. (This ink is only available in black.) If you put your boards through a muriatic acid/alkali wash, #6459 is recommended.

Cloth - #532 indelible is best. For nylon cloth, use #628

Concrete - #42M is recommended. It a dense ink with excellent is fade resistant and is weatherproof.

Fade Resistance - #42M is good for metal, lumber and concrete. If you need faster drying or you have to stamp on a-hard-to-mark surface, use #6606. #667 Opaque (fast) and #532 indelible (slower) inks also have good fade resistance.

Food Packaging - the following 4 inks all meet USDA guidelines for food packaging: #1250, #141, #620, #628.

Glass - With glass, you want a fast drying ink to avoid smudging. #445 Super marking, #6606 and #628 are recommended.

High Temperature Inks/Heat resistance - #6459 is good up to 650°F, but if it does not meet your needs, we can special order a specialized high-temperature ink.

Labels - For stamping non porous labels, #1250 is recommended. It works well on mylar and glossy papers. It is the best ink for foil. Pre-ink stamps with Ultifast multi surface ink can also be used.

For non-coated card stock stamps using ordinary stamp pad ink should work.

Leather - Use #532 indelible ink.

Metal Parts - The best ink for marking metal in terms of adhesion is #6459, but #6606 and #1250 also work well.

Mylar - #1250, #141 and #6606 all work well on mylar.

Nickel Plating - #6606 is recommended

Nylon - #628 is best.

Outdoor/Weathering - #42M is your first choice, but #141 is a good alternative.

Painted Surfaces - #620 ink will give a dense, waterproof fade resistant impression on painted parts. #42M and #667 opaque ink are also good. #1250 also works well.

Paper - Generally ordinary stamp pad ink is fine. If you you get feathering due to the porosity of the paper, then #532 Indelible or #445 Super Marking ink are a good alternatives. For high-gloss surfaces, use #445 Super Marking ink.

SELF-INKERS: Standard self inkers and pre-ink stamps usually work fine, but for glossy printed surfaces, use quick-dry ink in self-inkers or ultifast multi surface ink in pre-inks.

Photos - #1250 works best. #445 Super-marking ink is OK.

Plastics - A variety of inks will work on plastic, but some plastics such as polyethylene are hard to mark.
#620 (slow) and #628 (medium) work well on most plastics. #6606 (fast) will work on polyethylene. Untreated polyethylene is particularly hard to mark. Your best bet is #628.

Rubber - #1141 ink is the best for rubber parts. It doesn’t flake off when the surface is flexed, and it dries slowly enough to be usable in metal-frame SELF-INKERS.

Shrink Wrap - #620 works well. If you need temperature resistance, contact us. There are specialized inks we can get.

Silicone - Nothing really sticks to Silicone. #628 is best.

Stainless Steel - #6606 works well on stainless. So does #6459. #1250 will do at a pinch.

Tyvek - #620 is best. Dries quickly on the material, but stays moist on the pad for a long time. #6606 also works well.

Vinyl/PVC - #1141 rubber marking ink works best on this.

Waterproofness - most inks, with the exception of stamp pad ink, are water resistant. #667 Opaque, #532 Indelible and #445 Super Marking are particularly good. The ones to avoid are the plastic marking inks #620 and #628.

Wood - Stamping raw wood: indoor, use #532 Indelible, outdoor use #42M. For painted or varnished wood, use #1250 ink or #445 Super Marking ink.

Zeytel - is a hard-to-mark plastic. #628 works best.
