The technical FIELD

The present invention relates to printed products and to methods of printing of these products. The invention in particular relates to products printed using ink palette, in which individual ink satisfy the required combinations.

The LEVEL of TECHNOLOGY

Printed products and printing methods are well known. Also known products made using multiple print and color palettes with different ink. To reduce and increase the intensity of the individual colors in the appearance of the finished product, uses tone grayscale and print. Also known combined image, which is obtained by a combination of colors from a limited palette of ink to get the color out of the palette. Ink is determined using either the color space of L-a-b or a value in the color space of the L-C-H, or a value in the color space of the L-C-H-a-b. Determine the magnitude of the color difference Delta e (dE) for each color of ink to provide such a color change that is acceptable for each color palette of the printed ink.

Delta-e (dE) for each color represents the magnitude of possible deviation of the color ink used from the reference color, specified in the map full color space. This deviation mo is but to determine the distance between the specified and actual colors. Delta e is defined as a scalar without direction. In this form of the characteristic color of the ink the actual tolerance to change the color of the ink is represented by a sphere in a color space having a center at the position specified color and a radius equal to the Delta-that is, In practical applications where the color of the finished product are mixing the three basic colors palette, usually accumulating effects of changes in primary colors cause in the resulting composite colors exceeded the permissible level color deviations from the specified color composite. This tolerance level color deviations may result in the rejection of the finished product.

Thus, there is a need for a method of printing products, in which the specification of the color ink palette provides the appropriate ink, creating a printed color, which will have a valid level, color deviation from the specified color.

BRIEF DESCRIPTION of DRAWINGS

The figure schematically depicts an embodiment of the claimed invention.

The IMPLEMENTATION of the INVENTION

Printed article includes a substrate and an artistic image printed on the substrate. As products can be packaging materials, labels, packages, or other printed materials, known in the field. P is Delica can be any material, which is used in the printing industry as a substrate. Substrates include polymeric films and other polymer materials, various types of paper ranging from thin tissue paper to corrugated cardboard, Kraft paper, coated folders. The substrate can also be used metallized films and metal foil. The main substrate may be coated with drugs known in the printing industry for printing artistic image. The product can receive a protective and decorative finish after art image is printed onto the substrate. The printed substrate may be further or processed during manufacture, packaging, or the processing ends printing.

Picture art image printed products can be manufactured, configured, or simply stored in the electronic data file. Artistic image may include data relating to the desired or specified colors for the corresponding elements of the product. Specification of the artistic image and the color palette may include specification palette ink. Palette ink may include six individual specifications of colors, and may additionally include black ink. A limited palette of seven ink can be used, that is, the returns range from hundreds of multiple colors in the finished printed product. Each specification color in the palette ink may include the full value of the tone color in the color space of the L-C-H-a-b color space L-C-H or in the color space L-a-b. Color ink may be further defined by indicating the grayscale color model.

Specification palette, using values full tones and values halftone defines the color space. Artistic image can be created using the colors of a particular color space. To obtain a printed product, which accurately reproduce the drawings, the ink used in the printing process, should ensure that the reproduction is not only given full tone, but must also play the specified tones. The color of the finished printed product may include full tones and combinations of tones to obtain the colors of the entire color space.

The ink used by the printer must meet the appropriate specifications full color shades and halftones. In one embodiment of the invention it is necessary that the ink formulations were combined color difference dE full tone L-C-H-a-b, is less than or equal to 2. The person skilled in the art understands that the value of the combined dE full tone is simply a combination of dE values for each of the indicators L-C-H-a-b. Ink can be additionally is determined in accordance with the requirement, to 50% halftone had a joint dE no more than 3 in relation to 50% of the target halftone color.

The value of dE halftones can be determined, once the ink composition satisfies the requirement of dE full tone. A properly designed ink used to print the tonal range from 100% full tone to no tone at all. United dE halftones, preferably corresponding to 50% of the target halftone (better compliance defined as having a rate L is not greater than 1 relative to the target halftone), determined relative to the target tones. In one embodiment of the invention it is necessary that the combined dE was not more than 3. You may need to change the ink composition to satisfy the desired value of dE halftones. Ink with a changed composition should be tested to ensure that the desired value of dE full tone still satisfied.

The use of the compositions of the main ink that meet specifications full tone and 50% shading, reduces the likelihood of the raw composite colors in the finished product.

Specification palette ink may optionally include the use of printer ink formulations, which contain no more than two pigment. This limitation can reduce the variability of the composition and to reduce the likelihood of color changed the th made in ink.

Specification palette ink may also include the requirement of light fastness. The resistance is related to the stability of the color ink after exposure to radiant energy in a long time. Ink having a low degree of light fastness, can lose the appearance and fade even after exposure to light radiation of low intensity and low-energy spectrum.

Articles intended for use as a promotional product and product packaging, can be minimally acceptable levels of color light fastness, to ensure a stable and desirable appearance throughout the life cycle of the product. In one embodiment of the invention, the ink must have a lightfastness value of at least about 5. If the product is used under conditions of exposure to intense light radiation, the ink should have a value of light fastness 6, 7 or even 8.

To determine the light fastness of the ink composition can be used to test ISO 105-B02, in accordance with which the ink is exposed to light of the xenon lamp. In this test, samples of the printed ink and standardized samples of woolen cloth of blue color, with increasing resistance to fading and numbered accordingly this degree of stability from 1 up to 8, are simultaneously exposed to light xenon lamps up until samples of the ink does not reach the color differences from the dark pattern corresponding to the gray scale value of 3. At the same time, samples of wool fabric, exposed to light compared with dark samples of woolen cloth. If a sample of wool fabric 5 has reached the color differences in the gray scale value of 3, suppose that the ink have a lightfastness scale blue woolen cloth (BWS) at least 5.

Palette ink may further determine that the ink formulations support color space standard systems trial printing. Standard system test printing KODAK™, NEC™ have a color space within systems that can perform the proofs of complex artistic image. The color space of the destination. The choice of ink formulations outside of the color space standard systems trial printing can cause the art, the image may not be adequate to that which was printed more expensive process multiple print the finished product. Specification, which indicates that the ink composition has a score of test printing 1, means that the ink can be successfully used for making prints using undertie proofing printers. Inks that have a metric of trial printing 0 cannot be used to generate fingerprints.

The choice of a specific color palette determines the appropriate color space or a color spectrum. Appropriate color space can be used to narrow or limit the color choices made when developing a picture or create an artistic image for the product. Many products are designed using conventional color space, allowing you to limit the selected color, and can subsequently be printed with a conventional ink set. When the product has a uniform substrate and the size of the print areas, it can be one printing device to print a variety of products with different artwork and different composite color art images without the need to change ink used in the printing process.

In one embodiment of the invention, the first product may be printed in the desired quantity and the second product containing artistic image that differs from the first product may be subsequently printed on the same printing device without the need to change ink or cleaning procedures that are required when changing ink colors.

<> In one embodiment of the invention the color palette for printed products includes: the first ink, the color of which is set LCHab between about 61 and 64, 56 and 59, 224 and 227, -39 and -40, -39 and -42; second ink color which has values LCHab between about 53 and 56, 59 and 63, 358 and 4, 59 and 63, -1, and 4; the third ink color which has values LCHab between about 92 and 93, 87 and 88, 88 and 89, 2 and 3, 87 and 88; fourth ink color which has values LCHab between about 73 and 74, 80 and 81, 48 and 49, 53 and 54 and 60 and 61; the fifth ink whose color has a value LCHab between about 66 and 67, 64 and 65, 158, and 159 -60 and -61, 23 and 24; and the sixth ink whose color has a value LCHab between about 51 and 52, 49 and 50, 263 and 264, -5 and -6, -49 and-50.

Products can be printed using analog or digital print devices. The use of digital printing device allows to carry out trial printing products from the electronic data file of the artistic image. After a successful trial printing products digital printing device settings of the printing device associated with a trial printing can be combined with the data file of the artistic image. The data files of the artistic image and the settings of the printing device can be transmitted in many print and can be used in the us in many printing devices to obtain essentially identical products. The data files of the artistic image and the settings of the printing device can be transferred to many places print using any means known in the technical field related to the distribution of data.

Products can be printed using a combination of analog and digital print devices. Products can be printed using the methods of flexography or gravure printing. The product may include the proofs of rectangles, segments or spots. Each trial printed segment may consist of one color palette. In one embodiment of the invention, the segments include a composite color of the finished figure.
