Description
Technical Field
The technology relates to the technical field of laser paper printing of a web gravure printing machine, in particular to a registration device for printing a registration mark on laser paper on a DT-3000 registration system of Japan Sun corporation and a use method thereof.
Background
The gravure printing is the most common printing mode, and compared with other types of printing, the gravure printing has the characteristics of bright color, high anti-counterfeiting property, high printing durability, seamless property, high-speed continuous printing and the like. Therefore, the web gravure press is mainly suitable for printing large-batch color artworks and security prints, cigarette labels, wine labels and the like. The existing commonly used electronic shaft unit type gravure printing machine has the characteristics of small occupied area, short pre-registering time, high printing speed, capability of re-registering and the like.
The working principle of the automatic chromatography control system is that a photoelectric scanning head (namely, an aligning electric eye) on each color group detects the transverse and longitudinal position change between a reference color group triangular cursor printed on paper and a natural color group triangular cursor to output an instruction to a natural color group servo motor, a color group transverse servo motor pulls a printing plate roller to control transverse chromatography, and a color group main servo motor changes the synchronous speed with a host to control longitudinal chromatography. Two optical fibers are arranged on one photoelectric scanning head, one optical fiber is used for reading the reference color cursor signal, and the other optical fiber is used for reading the natural color group cursor signal. Typically, the first color set is used as the reference color set. The cursor signal is a signal reflected by a light source of the registration system after irradiating the paper with the cursors in different colors through the optical fiber, so that the positions of the printed cursors must have the same ground color, otherwise, the cursor reflection signals in the same position are different because of the interference of abnormal reflection signals of the paper.
The existing cigarette label printing production mainly uses white cardboard and white copper plate paper, and the reflected light of the base paper of the two kinds of paper is almost unchanged in the printing process, so that the photoelectric signal of a registration system is very stable. However, some printed products use special paper such as gold card paper, silver card paper, laser paper, etc., and in the printing process of this type of paper, the change of the reflected light of the base paper is large, especially the change of the laser paper with the light beam is the largest. The light beam laser paper has strong reflected light and large change of the intensity of the reflected light, so that the photoelectric automatic control registration system is greatly interfered and cannot be used for normally registering and printing. Therefore, when printing with the laser paper, it is necessary to add a base color to print, print the base color with the same width as the cursor on the position of the printing cursor to cover the laser paper, print the overprint cursor on the base color, and make the reflected light and electric signals of the paper near the position of the detection cursor completely consistent, so as to make the printing registration system work stably. However, this results in that when printing with the laser paper with light beam, a color set must be added to the normal printing color set for overprinting the base color of the cursor position. Such printing processes necessarily increase equipment length and power consumption, as well as increasing ink and solvent costs. Some manufacturers only require the manufacturers to widen the original paper roll by 15mm because the gravure printing machine has no redundant color groups, and the overprint cursors are printed on the 15mm original paper without adding the laser film on the 15mm original paper, thereby avoiding the influence of the glazing columns of the laser paper on the normal cursors. But this adds significantly to the cost of the paper. The cigarette label produced by company has 8 colors in normal printing process, and the problem of widening the base paper by 15mm is faced when the cigarette label is produced on a Sonde SAY820C8 type gravure press with only 8 printing color groups.

The invention relates to a using method of a registering device for printing a overprint cursor on laser light column paper, which is characterized by comprising the following steps: the using method comprises the following steps:
(1) installing the registered electric eye optical fiber: inserting the registration electric eye optical fiber into the electric eye optical fiber installation port of the laser light column paper, exposing the electric eye head from the registration electric eye cursor signal acquisition port, emitting an electric eye light source from the electric eye head to irradiate the laser light column paper, and reflecting a reflection signal on the paper back to the electric eye head from the registration electric eye cursor signal acquisition port;
(2) installing a double-layer optical filter: mounting the filter holder with the double-layer filter on the registering electric eye support, and fixing the filter holder by using a locking screw to ensure that the distance between the double-layer filter and the laser beam paper is 4-6 mm;
(3) selecting laser light beam paper registration parameters: dialing a registration electric eye signal gain switch at a laser beam paper gear, calling out a registration parameter setting interface on a parameter setting registration touch screen, selecting a standard registration parameter when printing the laser beam paper, adjusting the longitudinal fine tuning offset from 0.5mm set by a system to 0.3mm, simultaneously adjusting the transverse fine tuning offset from 0.5mm set by the system to 0.3mm, keeping other parameters unchanged, and shielding the detected interference wave outside the adjustment action of the registration system through parameter adjustment;
(4) printing and adjusting a registration cursor: the paper feeding path and the operation mode of the laser light column paper are not different from those of ordinary times, after the equipment is started, the laser light column paper roll is discharged from an uncoiler and then is fed by a driving roller, the laser light column paper roll is transmitted between a printing plate roller and an embossing rubber roll through a paper passing roller, the embossing rubber roll compacts the paper on the printing plate roller, an engraved pattern and an engraved cursor on the printing plate roller are transferred onto the paper through printing ink, a register electric eye is transversely adjusted to a cursor printing position, when the reflected light signal is obviously changed due to the fact that the printed cursor on the paper runs to the position below a register electric eye cursor signal acquisition port, the photoelectric conversion control box converts the reflected light signal into an electric signal and transmits the electric signal to an automatic register control system, and a printing cursor waveform graph is displayed through a parameter setting register touch screen;
(5) adjusting a printing waveform diagram: switching the interface of the parameter setting registration touch screen to a printing oscillogram interface, adjusting the waveforms of the color set cursor to be consistent when repeated appearance is required according to the adjustment of the waveform effect, and carrying out fine adjustment through fine adjustment screws in front and back of an electric eye until a stable oscillogram with the best printing overprinting effect is achieved;
(6) automatic control of printing overprinting: after the color set is registered with the pattern of the reference color set, the relative positions of the cursor waveform of the color set and the cursor waveform of the reference color set are locked in a wave gate, namely, the registration process of the overprinting cursor is finished.
The electric eye optical fiber mounting port of the common ivory board is vertical to the surface of paper, and an included angle of 25-35 degrees is formed between the electric eye optical fiber mounting port of the laser light column paper and the electric eye optical fiber mounting port of the common ivory board.
The invention principle of the invention is as follows:
in order to reduce the stronger reflected light of the laser paper, the inventor creatively arranges an upper laser paper electric eye optical fiber mounting port and a lower laser paper electric eye optical fiber mounting port which are obliquely inserted on the right side of the registration electric eye support, and the registration electric eye optical fiber is obliquely inserted at an angle of 25-35 degrees, so that the registration electric eye light source is obliquely irradiated on the laser paper, and the intensity of the reflected light of the laser paper returning to the electric eye optical fiber is weakened. The overprint cursor signal that DT-3000 registration system can discern is taken as the standard, puts the cursor signal to the biggest again, and the intensity of overprint cursor signal can reach the registration system requirement, and the wave form is as shown in the oscillogram shown in figure 8, has stronger light column interference wave 1, 2, 4 and 5 in 20mm wave gate width, and the influence of light column interference wave to the overprint is great, leads to the unable normal work of registration system.
In order to weaken the interference wave of the light column, the inventor tries to weaken the interference wave of the light column in a way of adding a single-layer optical filter in front of the cursor detection electric eye. Although the interference wave of the light beam is obviously weakened after the single-layer filter is arranged, the waveform diagram is shown in figure 9, but the ideal state is not achieved. Through repeated experiments, the inventor creatively designs the optical filter into a double-layer optical filter, and combines the polarizing filter A and the polarizing filter B together, so that the optical column interference wave is weakened to be very small, the normal cursor reading is hardly interfered by the waveform diagram shown in fig. 10, but the waveform diagram of the stronger optical column interference wave shown in fig. 9 occasionally appears, and the normal operation of the registration system is influenced. In order to solve the abnormal situation, the inventor considers that the error value of the interference wave detected by the registration system exceeds the registration deviation of the gravure press during normal printing by researching and analyzing the working principle of the registration system of the gravure press, and can shield the interference wave by adjusting the parameter setting of the registration system. The inventor creatively finely adjusts two registration parameters of longitudinal fine adjustment offset and transverse fine adjustment offset in a registration standard parameter setting interface, adjusts the longitudinal fine adjustment offset from 0.5mm set by a system to 0.3mm, and simultaneously adjusts the transverse fine adjustment offset from 0.5mm set by the system to 0.3mm, other parameters are unchanged, and the detected interference wave is shielded outside the adjustment action of the registration system through the adjustment, thereby achieving unexpected technical effects. After the two parameters are adjusted, the work of the registration system is stabilized, and the normal production requirement is met.
By adopting the technical scheme, the inventor invents a registration device for printing the overprinting cursor on the laser paper and a use method thereof on the basis of a DT-3000 registration system.
Compared with the prior art, the invention has the following beneficial effects:
1. compared with the existing cigarette label printing technology, the printing color group of the base color is less, and the production cost such as the ink consumption and the power consumption can be reduced. In the production process of the existing cigarette label printing, a base color is additionally printed when the laser paper of the light column is used for printing, the base color is printed at the position of the overprinting cursor, and the interference of the light column of the laser paper to a normal cursor can be eliminated only by printing the overprinting cursor on the base color, so that a color group is required to be added for printing the base color at the position of the overprinting cursor on the basis of a normal color sequence when the laser paper of the light column is used for printing, one printing color group is added, and the production costs of ink, electricity charge and the like are increased. Taking an example that a company produces 10 ten thousand boxes of laser beam paper cigarette labels one year, adding one printing color set requires about 120 ten thousand yuan of RMB, and the production cost of ink, electricity charge and the like is increased by about 10 ten thousand yuan each year.
(2) The laser paper of the light beam does not need to be widened by 15mm, so that the waste of cigarette label paper is avoided. In the prior art, when no redundant color groups exist, a paper manufacturer can only be required to widen the paper by 15mm, and a 15mm wide silver edge without a light beam laser is added to one side of the laser paper for overprinting cursor printing, so that the paper cost is increased. Taking 725mm wide width of the laser paperboard roll paper of the hard cigarette-packaging small box light column as an example, if the width is 15mm, the paper cost is increased by 2.07 percent. The Hongtashan produced by the company has 8 colors in a normal printing process, and the problem of increasing the cost of paper is faced if the Hongtashan is printed on a Sonde 8-color gravure printing machine. Taking a company to produce 10 ten thousand cases of cigarettes packed in a small box by using a light beam laser card paper, one side of the 725mm wide light beam laser card paper is added with a 15mm wide silver edge without light beam laser, and the paper cost is increased by 40 ten thousand yuan per year.
