Abstract

The present invention relates to a chromatographic check method for the synthesis of raster sheets with image lines. The present invention belongs to a printing technical field and solves the problem that various colors are printed on the image lines by chromatograph, the colors of images on the raster sheets are mixed to be difficult to be judged once chromatographic offset occurs, and displayed picture definition is affected. If the chromatographic offset occurs, that the chromatographic offset is judged and which primary color and which chromatographic direction are judged by comparison by human eyes is the problem requiring experience and delicate operation. The images are divided into the image lines parallel to a raster to be printed, and the width of the image line is less than a raster pitch. Chromatographic monitoring bars perpendicular to a raster direction are printed. The chromatographic monitoring bars are a group of chromatographic lines parallel to the raster, and the width of the chromatographic lines is less than the raster pitch. Chromatographic line spacing is not equal to the raster pitch. In a printing process, complicated comparison operation of inspection and judgement on the complicated images by means of extensive experience is prevented.

Description

The chromatographic check method that lenticular lenses and image lines are synthetic

Technical field: the present invention relates to printing technology, particularly the synthetic chromatographic check method of lenticular lenses and image lines.

Background technology: existing lenticular lenses audio and video products mainly are to be printed on the picture that is made of lines on paper, just picture are divided into many parallel lines, are referred to as the image line.Lenticular lenses is compounded on the picture seal paper that is made of lines, utilizes the refraction of lenticular lenses, on lenticular lenses, present variation, three-dimensional image effect.Because lenticular lenses is the laminated structure that is made of plastics, and has the arch that is parallel to each other of many projectioies rectangular on it, is referred to as grating, grating is very thin, and distance each other equates that distance between the two is referred to as pitch.Because the image line is also thinner than grating, on the image line, chromatography print multiple color, in case the cover color shift takes place, the image on lenticular lenses then produces color confusion, and is difficult to judge, the image sharpness that influence is presented.If the cover color shift takes place, compare by human eye, judge the chromatography dislocation, and judge any primary colours, to that direction dislocation, then be one and be sought after experience and elaboration.

Summary of the invention: the object of the present invention is to provide a kind of lenticular lenses and synthetic chromatographic check method of image lines that lenticular lenses is carried out the chromatography detection with chromatography monitoring bar.

For realizing purpose of the present invention, the synthetic chromatographic check method of described lenticular lenses and image lines is image to be divided into the image lines that is parallel to grating print, the width of described image lines is less than pitch, printing chromatography monitoring bar simultaneously perpendicular to grating orientation, described chromatography monitoring bar is one group of chromatography lines that are parallel to grating, described chromatography line thickness is narrower than pitch, and described chromatography lines spacing is not equal to pitch.

The present invention is a kind of improvement to the synthetic method of original grating and image lines, to the chromatography dislocation contrast work of the image lines of complicated image be changed into observing the contrast work of simple lines, figure or character, thereby judge whether the image lines chromatography of making misplaces, chromatography detection time in the manufacturing process of Suo Duaning greatly, be convenient to the adjustment to printing machine, the suitable common producer carries out the making of quick, large quantities of and various variation images.

Description of drawings:

The drawing of accompanying drawing is described as follows:

Fig. 1 is the carrier composition after lenticular lenses and the making.

Fig. 2 analyses and observe enlarged diagram for the A-A among Fig. 1.

Fig. 3 analyses and observe enlarged diagram for the B-B among Fig. 1.

The specific embodiment:

Below in conjunction with accompanying drawing, the embodiment of the synthetic chromatographic check method of lenticular lenses of the present invention and image lines is described in further detail:

As shown in fig. 1, this is an image, and it is to have two images to be synthesized together, and image is to be divided into many image lines 1A, 1B to print out, and two groups of image lines 1A, 1B that represent two width of cloth figure are arranged in Fig. 1, is intervally arranged between two group image lines 1A, the 1B.The synthetic chromatographic check method of lenticular lenses and image lines is image to be divided into the image lines 1A, the 1B that arrange two groups of spaces print, spacing between described image lines 1A, the 1B equals pitch, printing chromatography monitoring bar 3 perpendicular to grating 7 directions simultaneously, the height of chromatography monitoring bar 3 is positioned at the side of image greater than the height of image.Because image lines 1A, 1B, chromatography monitoring bar 3 are once to print simultaneously, as long as the chromatography that chromatography monitoring bar 3 is printed judges it is accurately, the chromatography of the printing of image lines 1A, 1B is inevitable correct.Described chromatography monitoring bar 3 is one group of chromatography lines 5 that are parallel to grating 7, and described chromatography lines 5 chromatographys are printed, and described chromatography lines 5 width are narrower than pitch, and described chromatography lines 5 spacings are not equal to pitch.

Because chromatography requires fuchsin, green grass or young crops, Huang, primary colours such as black to divide several times accurately to be printed on same position, in case the chromatography dislocation not only influences the definition of image, and influences the color of image.So, if find blue or green partially, the Huang etc. partially of the color that presents on it during observation chromatography monitoring bar 3, this primary colours dislocation is described, at this moment, need reset the parameter of computer-controlled printing machine, just can adjust the printing position of these primary colours soon.Because the color in the chromatography monitoring bar 3 is few compared with the color in the image, and it is single, judge easily, and can determine that primary colours dislocation in a short period of time and, avoid on complicated image, observing the complexity comparison work of judgement by means of rich experience to the beyond dislocation.

For example, image lines 1A, 1B, chromatography monitoring bar 3 are printed on the carrier 6 simultaneously, on blank sheet of paper or cardboard, respectively print a chromatography monitoring bar 3 on the both sides of image lines 1A, 1B, be printed on the various primary colours equivalent on the chromatography monitoring bar 3, be convenient to that so whole image is carried out chromatography and judge.When if chromatography is correct, chromatography monitoring bar 3 will present monochrome.Lenticular lenses is compounded on the blank sheet of paper that produces, and observes chromatography monitoring bar 3 up and down, and solid color to occur on the chromatography monitoring bar 3 be to illustrate that chromatography is correct when observing.Colour occurs when observing on the chromatography monitoring bar 3, the chromatography dislocation is described,, the cyan dislocation is described, then in printing machine, the cyan parameter is adjusted if cyan occurs, and the like, just this can learn the adjustment object of primary colours in the printing machine very soon.Several images synthetic then is divided into the similar two group image lines of image lines with the image of every width of cloth makes, and the image lines of a width of cloth image must be arranged in each bar grating 7, does not give unnecessary details at this.

Image lines 1A, 1B, chromatography monitoring bar 3 directly are printed on the lenticular lenses, make perpendicular to the lenticular lenses direction and see, chromatography monitoring bar 3 presents solid color, illustrates that chromatography is correct, otherwise the dislocation of explanation chromatography.Whether whether chromatography is accurate can to learn image lines 1A, 1B equally very soon.Be printed with chromatography figure or literal at chromatography monitoring bar 3, described figure or character are some simple figure or characters, chromatography figure or literal are divided into chromatography figure or text line, the width of described chromatography figure or text line is narrower than pitch, and described chromatography figure or text line spacing are not equal to pitch.Because figure or character will be divided into lines, be mixed in the chromatography lines 5, as long as observe the figure or the character of chromatography monitoring bar 3, whether image lines 1A, the 1B chromatography that also can judge very soon in the image be accurate like this.Though figure or character are printed by chromatography, but its color that presents still is monochrome when chromatography is correct, and figure or character are very simple, judge easily, have avoided relying on rich experience to carry out chromatography on the image of complexity and have observed the complexity comparison work of judging.
