Screen Equipment Tech
The HIX Made in the U.S.A. Manufacturing Process
• Every HIX screen printing press is totally designed, engineered, and manufactured at our Midwestern factory.
•The HIX “tool-less” Premier Manual Rotary Printer upper print heads, rotary wheels, print arms, and optional shirt boards – all made from HIX exclusive cast aluminum alloy.
• All castings are made from permanent steel cavity molds to ensure dimensionally consistent tolerances on all components.
• Floor model and bench model structural components are made from welded .250″ gauge steel tubing.
• The center shaft is made of hardened 1075 alloy solid bar stock that is welded into the steel vertical support stand.
• Both upper and lower rotary wheels are centered on the shaft with independent sets of tapered roller bearings, allowing the free movement of both upper and lower units as well as superb stability.
• An adjustable center nut allows periodic adjustments to compensate for any wear that may occur.
• Screen frame clamps and cross-tubes are made from steel. These parts are zinc plated for easy clean up and maintenance.
• Easy-turn, spring-loaded adjusters make loading and removing screens a cinch.
To allow the modular interchangeable feature of the print heads and print arms, precision casting and millwork are essential in the manufacturing process. Our in-house aluminum foundry uses state-of-the-art cavity mold casting equipment. The parts then move to computer-controlled CNC milling machines where we maintain the tightest ± tolerances in the industry. With this manufacturing approach, we can offer consistent interchangeable parts that allow modular construction and expandability with a precision fit.
All heads down: The ability to print with all print heads simultaneously, independent of other colors.
Note: Most printers will print at any station, but not independent of the colors or with two or more print heads in the “down” position. This means that all colors must print at that station. This is not true of all heads down printing.
Brake arm: Stops the lower rotary wheel or speed table in the print position.
Brake wheel: Controls braking action of the lower rotary wheel or speed table (printing stations).
Contact registration: Aligning screen directly on contact with artwork on printing surface.
Dual sleeve platen: Attaches to print arm to allow printing of two sleeves at the same time.
Gas Spring: Raises screen from print surface to “up” position in a controlled manner.
Flash/Flash Cure: A high intensity IR heating device that is moved over a wet print. The print is flash dried. It is not cured, only ready for an additional wet ink to be applied on top of the previous.
“H”-Arm: A rigid cast aluminum ‘H’ design which minimizes deflection and allows true “on contact” registration.
Index (print head): Boot heel-shaped nylon part located on print arm for gross centering of print head.
Jacket hold down: Adjustable clamping platen to allow printing on jackets, lined or unlined.
Manual cap platen: Attachment for printing caps.
Micro registration: System for controlling fine adjustment of the X and Y-axis of the screen to the proof.
Off contact: Distance between print side of screen and printing surface. Parallel alignment of the screen frame to the shirt board for proper “snap” off the printed substrate.
Pin registration: Screen registration system for precise exposing and registering of printing screens.
Platen: Also referred to as shirt board.
Print head: Complete assembly from upper rotary wheel to screen clamp, one per color, attaches to the upper wheel and accepts either standard or micro registration.
Print arm: Holds/supports shirt board or other types of platens.
Ratchet Handles: Locks the micro registration plates to prevent any movement in registration.
Registration index guide: Device used to line up print head with print arm.
Screen clamp: Holds screen frame. There are two types: side clamps and back clamps.
Screen inclination: Angle of the screen from front to back in relationship to printing surface.
Sequential lift: A biaxial print head that lifts straight up (level to the platen) then away from the print.
Vellum: A paper substrate made from plasticized cotton that is thin enough to be virtually transparent to strong light. Used to produce positive images for screen exposure.
Speed table: Lower rotary wheel with print arms and shirt boards.
Spot Cure: See Flash/Flash Cure
Squeegee stop: Device to rest squeegee between print strokes.
Trap (film): Usually refers to the proof positive film, which traps or outlines most of the other colors, or shows the most detail of a design (usually this is the black on a white shirt).
Vacuum platen: Attachment to allow printing on sheet substrates, transfers, vinyl, metals, etc. A wood-base platen with a stainless top that includes a built-in vacuum hold-down.
