Existing making sheet technology is a cover complicated technology necessary owing to adopt laser photocomposing machine, at first by film setter output film film, carries out artificial layout, printing down then to generate the PS version that can print at last, and its technological process is as follows:

Technological process:

Numeral page info → film (film) output → layout → printing down → go out PS platemaking need pass through the loaded down with trivial details technical process of above-mentioned complexity, high material consumption, environmental pollution is big, labour intensity is big, the used time is long, automaticity is little, energy resource consumption is big, because complex process, easily distortion of original image, the distortion rate height, the mistake that human factor causes accounts for significant proportion, the waste paper rate height, and inevitable cost increases.

Summary of the invention

The purpose of this utility model by using the utility model (numeral is platemaking machine directly) to make mask-making technology easy, quick, is enhanced productivity exactly, improves the printing level.

Advantage of the present utility model and effect:

Compare with technology with domestic, technology is easy, makes technology easy by using the utility model, and is as follows:

Technological process:

Numeral page info → digital sample printing → lot sample, revise → forme output

By using the direct platemaking machine technical process of digitlization to simplify greatly, automaticity improves as can be seen;

1, technological process is short, and publication time shortens;

2, energy consumption is low, greatly energy savings;

3, become version rate height;

4, the plate-making cost reduces;

5, labor strength reduces;

6, avoided the dot loss of traditional handicraft;

In addition by using the utility model to make printing process also bring revolutionary variation

1, big shortening is used for the time of alignment and color correction

2, reduce paper, printing ink loss

3, improve the printing machine operating efficiency

4, make price more competitive

5, more this change production procedure

5, utilization and innovation new technology

Description of drawings

Accompanying drawing is the conceptual plan view of the direct platemaking machine of the utility model digitlization.

The specific embodiment:

Be described in further details below in conjunction with drawings and Examples:

Embodiment 1:

The direct platemaking machine of a kind of digitlization, it is characterized in that it is by image processing software 1, data analysis processing module 2, laser instrument driver module 3, optical scanner image-forming module 4, carrying printing plate module 5,6 six parts of whole time-sequence control module are formed, wherein image processing software is mounted on the common computer, the data analysis processing module is that digital document is sent to the laser instrument driver module in the suitable position of reasonable time, it is by grating encoder 8 and system synchronization, the optical scanner image-forming module is by stepper motor 9 optical lens and optical fiber solid matter 11, leading screw is led 10 rails and is formed, the carrying printing plate module is by cylinder 7, motor 12, form, whole time-sequence control module mainly is that the control of integral body is coordinated.

Embodiment 2:

The direct platemaking machine of making according to the utility model principle of digitlization claims CTP again, and the plate that it is selected for use is that laser wavelength is 830nm to the infrared light activated temperature-sensitive version of 830nm.

1, the laser facula size is determined:

Point (dots) spacing h: $h=\frac{\mathrm{linch}}{2540}=\frac{25.4}{2540}=0.01\mathrm{mm}=10\mathrm{\μm}$

The big or small d of point (dots): $d=h\×\sqrt{2}=10\×\sqrt{2}=14.14\mathrm{\μm}\≈15\mathrm{\μm}$

Laser facula size D: $D=d\×\sqrt{2}=15\×\sqrt{2}=21.21\≈21$

2, burn the needed time t of a point (dot):

If: the energy efficiency of imaging is η=50%

The pulse duty factor that is chosen to picture is 80%

Then have following equation to set up:

Every some imaging time of the Power x of ablation point unit are＞plate threshold value

Every some imaging time of the Power x of ablation point unit are＜plate threshold value * 10

3.1CTP the time T that cylinder whenever turns around

Time=90000 * 1.3 * 10 of T=cylinder dots * each dos of ablation weekly ^-6=0.117s

The rotation speed n of cylinder: n=60/0.36=1667r/min

Determined multiplying power, and the parameter of leading screw and stepper motor of power, the camera lens of rotating speed, the laser instrument of cylinder by CALCULATION OF PARAMETERS, again each several part has been carried out assembly and adjustment, made the each several part co-ordination, the technical indicator that machine can reach is as follows:

1, the maximum breadth 830 * 645mm of breadth

2, plate 830nm temperature-sensitive version

3, resolution ratio 2540dpi

4, same 10um of precision

5, image taking speed is 7 minutes

6, power 1.5KW

7, voltage 220V 50HZ
