Table Top Etching Press InformationPressure System:
Printing pressure is applied by lowering the upper pressure drum onto the press bed using the pressure adjusting screws. Micrometer pressure dials are supplied with each press to allow consistent pressure application and repeatability. The upper pressure drum may be raised 1.25" above the bed for relief printing.
Half-inch blanchard ground aluminum tool plate with a phenolic-resin sheet bonded to the top and bottom surface provides a durable work surface. This surface will withstand all chemicals used in the printing process, very high pressure without embossment problems or loss of printing pressure, and cleans up easily. Uneven printing pressure is eliminated by independently adjustable precision ball bearings supporting the bed.
Three-quarter inch by five inch aluminum is paired and machined simultaneously to provide a very accurate and sturdy frame unit. One inch diameter cross bars bolt the frame together. An aluminum frame provides maximum strength, yet reduces the press's weight considerably, making it a more mobile unit.
Pressure and Drive Drums:
Welded drum shaft, support baffles, and heavy wall drum stock are machined to precise specifications as a concentric unit. Maximum drum shaft support is achieved by two self aligning ball bearing support units. This allows the upper pressure drum independent vertical end-to-end travel. All drums are nickel plated. The Pressure Drum is available in standard 4.5" or optional 7 1/2" diameter. The 7 1/2" diameter upper pressure drum option equips your press with a 7 1/2" diameter nickel plated Upper Pressure Drum as opposed to the standard 4 1/2" diameter nickel plated drum. The advantage of this option is a larger diameter Upper Drum will allow the press operator to print with greater pressure with less effort. Although either drum diameter offered will produce excellent results when printing, we recommend the 7 1/2" diameter drum when using heavy pressure.
Internal Bed Stops:
Bed Stops secure the moving press bed to the press frame. Allows full press bed travel and maxamizes printing area. This feature is a must in today's safety conscious work environment. The internal bed stop design allows full printability of press bed.
Bed Drive System:
Effortless hand cranking is made possible by our double reduction chain and sprocket drive system with a 6:1 ratio. Polyethylene wear strips attached to each side frame assure minimal bed friction. "See-thru" chain guard covers allow easy inspection of chain lubrication.
All steel press parts are protected by nickel plating, anodizing, high quality paint, or powder coated finish.
