HOW TO CHOSE A SQUEEGEE

60-65 SH squeegees are very soft; they are usually used to print on ceramic and with glitter inks.
70-75 SH squeegees are recommended for printing on glass and on garments.
80-85 SH squeegees are used to print with high-speed automatic machines, to print on CDs, credit cards, electronic circuits, small objects, where high precision is required.
SURFACE: if the item you have to print has an rough, non-planar surface, the most suitable squeegee durometer is between 60 and 70 sh. If the surface is smooth, a harder durometer squeegee, between 80 and 90, should be used.
MESH: if a high mesh count (mesh very thin!) is being used, you need a harder squeegee (80 or 90 sh); if you are printing with glitter ink (which has large flakes of shiny, plastic material that have to pass through the mesh) you should use a softer squeegee.
INKS: the more aggressive inks, such as UV inks, cause more damage to the squeegee than a standard water based ink. The harder the material, the more solvent resistant the blade. Therefore, to eliminate swelling and chemical breakdown, use a harder durometer squeegee
INK DEPOSIT: a soft squeegee will deposit a thicker layer of ink than a harder squeegee.
AUTOMATIC OR MANUAL: hard durometer squeegees are normally used on high speed automatic machines (high degree of abrasion that occurs during a production run). Softer durometers squeegees are typically used for low-pressure low speed manual and semi-automatic presses.
