A trick to restore the fat-sensitivity of the rubber roller

Ink transfer rollers, leveling rollers and form rollers that play the role of bearing, transfer and transfer in offset presses are rubber rollers. These rubber rollers are often used in conjunction with cross-ink rollers and heavy rollers of different materials. In general, the higher the grease-s ......

Three cases of common thorny problems in offset printing

Offset printing is currently the main printing method for printing companies. The failure of lithographic offset printing due to the output system is the main reason for the inaccurate overprinting, uneven ink color, and even the failure to print, which delays the delivery time. This is one of the ......
