Fully Automatic STOP Cylinder Screen Printing Machine (4-post screen lift type—flagship model), linked with Feeder

QL 4-post screen lift type, as SPS’s flagship model, is based on the superior German lineage classic: the “Original SPS STOP Cylinder Principle” (advantages: highest run speed, printing quality, operator convenience and comfort, ever seen in the market), upgraded with the unique 4-post screen lift design: large opening under screen allowing comfortable operator access, for observing sheet flow (runs with screen lifted), and screen cleaning, significantly upgrades setup efficiency and comfort degree, plus the primeline luxury class optimization, for modern high speed automatic screen printing processes to use.


A) Advanced Offset Feeder: No crossbar obstruction over front of feeder. Operator can stand up for comfortable operation. Both sides open, convenient for pile adjustment. Steel plate goes to the floor, easy manual load or w/pallet jack.

B) Feeder Head: Advanced feeder head with controls for multiple blast air for sheet separation, vacuum strength, suction cups angle/spread position, skew correction provides an advantage when running deformed sheets.

C) Infeed Conveyor Vacuum: Vacuum volume fully opened or closed, and adjustment can be increased or decreased incrementally.

D) Screen Setup Space: Top frame 4-post lift, screen tilt, exit belt fold down, screen slide-in loading from operator side, central screen adjustments + pneumatic frame lock-in. Provides maximum comfort and access for operator fast and convenient settings for cleaning screen, cylinder, + other adjustments.

E) Screen Adjustment: Screen adjustments centralized, convenient for adjustment at one-position, from delivery end or operator side.

F) Screen Holder Frame: Designed with screen tilt to gather ink at print end, prevents flow-back and dripping through mesh holes of low viscosity inks.

G) Screen Off-Contact Distance: Screen to cylinder distance 1.5mm. Lower off-contact improves registration tolerances. Minimizes mesh to be pressed down by squeegee for increased life of screen. Less mesh stretch and deformation.
H) Squeegee: Optional German RKS C05 carbon back-plate squeegee (one piece). Strong in support (no bending) and light-weight. Changed in 1 second by switching a nearby pneumatic clamp. Carbon plate helps dissipate static.

I) Squeegee Level Adjustment: Only 2 seconds for automatic setting by machine from pushing 2 buttons, fast and constantly accurate always, regardless of operator skill level.

J) Squeegee Pressure: Pneumatic + electronic + hydraulic triple controls (stabilizing), automatic equalization. Includes dynamic automatic adaption to level variance.

K) Squeegee Angle: No need of tool for adjustment. Squeegee blade position remains unchanged and constant, adjustment is fast and convenient.

L) Print Stroke: Print stroke digitally settable according to sheet length. Squeegee accurately falls beyond grippers in settable range. Lengthens life of screen and squeegee. No risk of ripping screen.

M) Delivery Conveyor: Belts run in variable speeds. First synchronized with cylinder speed (delivery-sheet out). Secondly synchronized with dryer conveyor speed (transferring sheet to dryer). No risk of scratching sheet.

N) HMI: Main HMI placed at operator eye level. Clear icon and text display for operation conditions, error displays, for easy operator use & control.

O) Sheet Side Guides: Vacuum suction and pulling from bottom side, prevents damage to sheet surface (with optional vacuum-push mode for thicker / heavy sheets).

P) Anti-Drip: Squeegee with optional swivel drip pan device, to collect ink drips from squeegee, effectively prevents print quality defects due to ink drip.

Q) Anti-Splash: Designed with solution against risk of splash (out of screen) of low viscosity ink (varnish) during high speed runs. Splash guards synchronously activated open/close along with screen clamping/release action, convenient for production runs using low viscosity ink.

R) High Speed (3000 p/h~): Equipment can comfortably adapt to long time high speed run up to max. nominal 4500p/h (mechanism weight-load well balanced and fine-tuned, thus low in vibration, noise and wear).

S) Maintenance: Automatic oiling for all mechanisms, with oil level detection and warning indication. No need for frequent oiling, lessens work burden and lengthens life of mechanical functions (often seen used for over 35 years).
