OFFSET PRINTING MACHINE
Offset printing machine is an ordinarily utilized printing system in which the inked picture is exchanged (or “counterbalanced”) from a plate to an elastic cover, at that point to the printing surface. At the point when utilized as a part of blend with the lithographic procedure, which depends on the repugnance of oil and water, the balance strategy utilizes a level (planographic) picture transporter on which the picture to be printed acquires ink from ink rollers, while the non-printing region draws in a water-based film (called “Wellspring arrangement”), keeping the non-printing zones without ink. The advanced “web” prepare sustains an expensive reel of paper through an extensive press machine in a few sections, commonly for a few meters, which at that point prints ceaselessly as the paper is encouraged through.
a. One touch:
One touch pre-registration, thousand jobs storage / management, internet remote diagnosis HMI touch screen by German made Bosch Rexroth.
b. Two modes:
Full rotary or semi-rotary (intermittent) two modes can be selected for various job needs.
c. Three sections:
Semi-rotary (intermittent) mode by three sections in-line:
Sec1. | unwinder, corona, web cleaner, cold stamping, laminating, back / adhesive side printing by continuous full rotary web feed. |
Sec2. | UV offset, UV flexo, rotary die-cut stations by semi-rotary web feed. |
Sec3. | cold stamping, laminating, back / adhesive side printing, rotary die-cutting, waste rewinding, web rewinding, slitting, sheeting by continuous full rotary web feed. |
Ps. | Due to semi-rotary (intermittent) mode / section web feed is forward then backward then forward movement, not only web tension changes, UV triple times curing possibly overheat, to do cold stamping, laminating, back / adhesive side printing, waste rewinding, web rewinding, slitting, sheeting etc by in-lined full rotary section is definitely much better / more practical than to do by semi-rotary (intermittent) section. |
d. Four servos:
Shaftless full servo drive printing stations (4 servos / computers per station for cylinders, damping driving and longitude, lateral registration) and web feed / tension control diamond finished servo feed drums by German made Bosch Rexroth.
e. Five cylinders:
AniPrint inking system by much shorter inking route and same diameter Ink fountain (Anilox), Form, Plate, Blanket, Impression 5 cylinders in one offset printing ensures ghost free printing, much quicker job set up time and much less waste especially compare to conventional offset.
C M Y K / R G B
Labelmen’s digitalized offset press innovated AniPrint anilox inking system and Pantone G7 color management, presented easy operation and waste reduction features:
Ink layer thickness:
Double ink layer thickness (3~4u) than conventional UV offset printing (2u); four times thicker ink layer than conventional sheetfed offset printing (1u); change to lower meshes Anilox ink fountain cylinder is around equal ink layer thickness as flexo printing (4~5u).
f. 6 kw:
6 kw cool UV with thermal insulation device reduce lot of heat, plus advanced web tension control system create possibility to print shrink film by semi rotary mode.
g. G7:
Color management is according to Pantone G7 method.
h. Single & re-passes:
Single pass complete all jobs in-lined possibility.
2nd pass also available for if needed as standard unit.
i. Double thickness:
Ani-print UV offset ink system is double ink layer thickness than regular’s.
Can do opaque white coating without add UV flexo station.
j. Triple uses:
Wet UV offset, Waterless UV offset, UV letterpress printing triple uses possibility.
l. Multiple functions:
German made E+L EPC web guider, corona, German made Technotran auto dampening circulator, auto ink wash, 2nd pass printing scanner, German made E+L register camera & monitor, edges trim slitter etc as standard;
UV offset, UV flexo, back / adhesive side printing, cold stamping, laminating, rotary die-cutting, USA Martin Automation butt splicer & STR turret rewinder & non-stop waste rewinder for full-automatic web reel change as none-stop printing etc can be the combined configuration;
Web cleaner with static eliminator, Monitor PS plate puncher & bender, flat-bed hot stamping, embossing, die-cutting etc can be the options.
