Squeegee Blade Profiles
Name Pic Descr Typical Applications
G1 One of the most popular profiles, squared edged 90 deg blade used for a wide range of printing applications where a thin ink deposit is required, for example the four coloured process. This blade will print on many different substrates, a soft blade for porous surfaces a harder blade for more smoother surfaces. Textiles, ceramics, tiles, coarse surfaces, graphics, large format prints, printed circuit boards
G2 The single bevel edge blade (60 & 45 deg) is used for printing onto non-absorbent surfaces such as plastic, glass or metal. Conforms easily to irregular surfaces while maintaining excellent ink deposit. Widely used on container printing. Non-absorbent surfaces, plastic, glass, metal
G3 The double bevel edge blade (60 & 45 deg) provides excellent control for direct printing onto a wide variety of cylindrical surfaces, also fine print for textiles. Controls ink flow with minimum force. Glass, textiles, cylindrical surfaces
G4 The double sided flat edge bevel blade is used in direct ceramic printing. The profile also allows for maximum ink shear on multiple substrates. (flat edge is approx 1mm to 3mm wide depending on the blade width). Provides additional ink deposits, allows increased downward force on automatic machines. Glass, ceramics
G5 Square edge Composite Dual hardness blade, a 90 deg hard backing supports a full face of softer squeegee material, usually 65 or 75 shore, that does not flex of roll over, giving excellent ink shear. The softer edge allowing for good ink deposit.
G6 Square edge Composite Triple hardness blade, a 90 deg central strip supports two faces of softer squeegee material, usually 65 or 75 shore. This combination gives the printer the responsiveness of a soft to medium hard blade without the undesired flexing created by increased secondary force squeegee pressure. This is excellent for printing on high mesh counts (120/140 threads/cm) with high tension, and increased squeegee pressure making it useful in large format high speed flat bed and cylinder machines. Excels in printing four colour process work or half tone jobs on automatic presses. Graphics, printed circuit boards, large format high speed flat bed and cylinder machines, four colour process, half tone jobs
G7 G7 to G15: Composite tipped blades, produced in all the main profiles. A soft squeegee tip is bonded to a 90 deg hardness blade. This stops roll over and squeegee vibration on high speed automatic machines. High speed automatic machines
G8 High speed automatic machines
G9 High speed automatic machines
G10 High speed automatic machines
G15 High speed automatic machines
G18 Used where high volume deposits are required, in range 60-75°A. Textiles
G20 Enables precise blade angles to be maintained with low squeegee pressure.
G25 Used in the electronics industry where very rigid blades are needed to deposit thin, even layers.  
The Optima range comprises two distinct types of blade:
MT is a moulded blade with four usable radius edges and is unique in not having a moulded seam.The radius edge offers good in-flow for single colours.
CT is a precision cut blade that incorporates our "Edge of Perfection" standards on all four edges enabling the high quality required for the four colour process.
Many CD printing processes will require a combination of both MT and CT types of Optima blade on a single machine to optimise both print resolution and consistency.
Other Blades
Rounded edges on the G1 is for situations where an increased deposit is required for increased colour opacity of gloss level on uncoated surfaces. This is usually carried out after the squeegee blade has been fitted into the holder, the operator ‘breaks’ the squeegee edge by rubbing very fine abrasive paper along the edge of the squeegee

The full rounded blade, used in textile printing to increase dye penetration, this profile forces the print medium through the screen in two or more printing strokes. This product is usually a cast finish blade produced in short lengths (1.5 mtrs approx)
