DI Direct Imaging Technology

DI is the abbreviation DI of Direct-Imaging (Direct Imaging). The printing unit is based on a traditional offset printing press, using traditional offset printing or waterless offset printing;
DI operates in an all-digital printing workflow as an output. The DI model has the highest degree of automation in the offset press and intelligent operation;
The imaging system and plate of the DI printing press: The DI can directly accept digital files before printing, plate making and printing on the machine, simplifying the processes and personnel, and improving the quality.
The main technology of DI presses Imaging technology Presstek laser system; Creo laser system plate Presstek Pearldry plate; No-touch thermal printing principle Presstek waterless offset printing; Traditional offset printing workflow All digital workflow

Presstek System Profile
The laser beam emitted directly from a silicon resin on the surface of titanium metal intermediate layer heat to heat the intermediate layer and the surface layer of titanium metal vaporization, the exposed portion exposed polyester plates yl graphic region not exposed region is formed a non-graphic areas advantages
No need for fountain solution and dampening system, the operation is simple and convenient. The first one can basically meet the standard with a larger color space than traditional offset printing. The waterless version of the graphic part is slightly lower than the surface of the printing plate, can carry more ink, and at the same time there is no dilution of the fountain solution, the dot enlargement rate is small, the higher ink density can be printed, the color of the print is bright, and the contrast is strong. Environmental Printing Production Method Thermal System Introduction
With Creo “SQUAREspotTM” - square spot thermal laser technology, it has a very high dot quality and can print a very high number of lines, the dot calibration is simple and reliable, the printing ink is fast, and the dot gain is small

* Technical Features of Creo System Imaging Technology Creo "Spot-Point" Thermal Laser, with a variety of press-free thermal plate Presstek PearlGold, Heidelberg Saphira Advantages Accurate and stable network sites; Compatible with traditional offset printing; Platemaking costs are very close to traditional offset printing representative machines Heidelberg SM 74 DI

Comparison between DI and traditional offset printing

Simplification of the process ;
Automatic printing operation, from automatic plate to automatic cleaning;
Full digital flow, prepress data directly remotely control the ink fountain area default;
Stable and reliable, simple and convenient calibration;
The imposition efficiency has been greatly improved, the overprint accuracy has been greatly improved, and human error has been reduced.

Improvement of printing quality
Digital proofing, proofing and printing, printing as long as the standard density can be printed, reduce the color, downtime;
Based on ICC-based color management, accurately simulates the printer color space with the specified digital proofing device;
Instant proofing, last minute modification;
Directly to the computer, the computer can fully implement standardization and data quality control, and can completely reproduce 1-99% of the outlets on the printing plate. The outlets are more abundant and continuous.
The quality of outlets has been improved: sharp edges, faster inking, small dot gains, higher printable densities, more vivid prints, and more contrast;
Reduce the cost of outputting the cost of filming and proofing;
The cost of printing and even syrup;
