Squeegee and flood coater travel is servo-driven for stable low to high speed control, with linear guide rails and cog toothed belt for smooth, precise, vibration free printing, ensuring absolutely even and uniform ink deposit. Touch screen digital setting of this print parameter can be stored, saved, and recalled from the touch screen for repeat jobs and/or common applications. Reduces setup and changeovers.K. SERVO DRIVEN PEEL-OFF

Digitally controlled servo peel-off distance of start/end point can be set relative to image size, with variable speed and height control. Touch screen setting of this print parameter can be stored, saved, and recalled for repeat jobs and/or common applications. Reduces setup and changeovers.L. BALL BEARING MICROMETER DESIGN

Special ball bearing micrometer design instead of thread bolt type adjustment. This is designed to prevent stripping out and offers play-free registration without backlash during setup.M. FRAME REGISTRATION

X/Y Three (3) micrometer registration adjustments for screen alignment of screen image on the substrate with numbered value for repeatability and standardization. Once alignment is completed the frame holding rails and screen can be pneumatically locked and secured.N. PRINT TABLE MOVEMENT CONTROL

Print table motion cycle driven by top-class servo motor, using swivel arm system guided by linear rail for consistent repeatability.O. PNEUMATIC FRAME LOCKING

System with check valves / airlock and four-sided frame holding assembly ensures rigidity and high stability.P. DIGITAL PRESSURE EQUALIZATION

Print and flood coater pressure is digitally settable with fully automatic pressure equalization system and auto-leveling function controlled by touch screen for precise balance and consistency of printed ink film layer. Digital setting of print parameter can be stored, saved, and recalled from the touch screen for repeat jobs and/or common applications. Improves print quality and reduces setup and changeovers.Q. NO-PEEL FLOOD COATER FUNCTION

No-peel flood coater function has digital settings that can be saved, recalled, and adjusted from the touch-screen.R. HIGH-PARK OF SQUEEGEE AND FLOOD

Squeegee & flood high-park allows screen loading and unloading without removing squeegee holder and flood coater. This facilitates rapid setups and change-overs.S. PRINT SELECTION MODE

Choice of flooding before the print stroke, flooding after the print stroke, or higher cycle speed-flood while screen lifts to full "up" position, and after specified number of print strokes (from 1 - 5 times in one cycle). Digital setting of print parameter can be stored, saved, and recalled from the touch screen for repeat jobs and/or common applications. Reduces setup and changeovers.T. SET NUMBER OF PRINT CYCLES

Digital setting for the number of print cycles necessary for printing job and the machine will stop running automatically upon completion of set amount. Print parameter can be stored, saved, and recalled from the touch screen for repeat jobs and/or common applications. Reduces setup and changeovers.U. FRAME HOLDER PIN REGISTER

Screen frame holder is equipped with rear registration pin system for fast and repeatable frame position centering to reduce setup time.V. LINEAR GUIDE RAIL CYLINDER FOR SQUEEGEE AND FLOOD COATER

Linear guide rail cylinder for smooth vibration-free squeegee and flood coater up and down movement. Includes precise micro adjustment control with numbered fine-tuning depth, skew-angle (snowplow feature), and numbered swivel angle of squeegee and flood coater. Allows the highest degree of repeatability, reliability, accuracy, and extremely precise even pressure of the squeegee and flood coater. Overall print quality is optimized.W. FOUR-POST LOCKING

Unique four-post locking system ensures that no lifting of print assembly or corner post can occur, while keeping perfectly parallel to the print table at all times during the printing sequence. This benefit allows controlled, consistent even ink deposit, while preventing mesh elongation. Accurate off-contact distance is effectively kept across the entire the surface of the mesh.

X. SAFETY LOCK FOR SCREEN CLEANING

Screen cleaning safety switch located at the rear of the machine completely disables any start function to protect operator when cleaning the screen. Operator can completely lock out the machine to prevent any chance of machine activation.

Y. PRINT HEAD SAFETY GUARDS
