HOW TO CHOSE A SQUEEGEE 65 SH squeegees are very soft; they are usually used to print on ceramic and with glitter inks. 75 SH squeegees are recommended for printing on glass and on garments. 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.
