Definitions
- the present invention is related to digital inkjet printing, proposing an application system of this type of printing with individual drying of the application of each ink, so that the effects of displacement of the inks on non-absorbent media are eliminated. or poorly absorbent, which results in high quality printing results.
- Inkjet printing is done by the individual projection of inks of four basic colors (cyan, magenta, yellow and black), by means of which combinations all the necessary colors are obtained, using inkjet heads , which project the inks on the surface to be printed, by piezoelectric systems, or by mechanical drop ejection systems.
- These scanning printing systems can have a drying medium that in each pass of the printing dries the ink that has been deposited, so that the amount of ink that can be deposited in each pass is limited depending on the drying, so , depending on the nature of the surface to be printed and, particularly, on the absorption thereof, higher or lower quality prints can be made by one or multiple passes on the same point.
- the ink supply capacity by the injection heads is of the order of 150 ml / min
- the limit of the ink supply in successive layers also depends on the conditions of the ink on which a ink is to be applied. back ink layer, as ink flows over a previous layer of totally dry ink, distorting the print.
- the amount of ink that can be supplied is very limited, since the printing ink is provided at one time, without the possibility of waiting for the ink to be absorbed by the printing surface to make passes later on.
- the possibility to deposit layers of ink superimposed with this type of printing is to multiply the number of injection heads in consecutive groups, applying a drying between the deposition of each layer and the next one, in an equivalent way to the one of printing by scanning, But this possibility has such a high economic conditioning that it is practically unfeasible.
- an inkjet printing system is proposed, with which an advantageous effect is achieved with regard to color stability, since drying of the inks that are applied occurs partially after application. of each ink, with the application of the ink and its drying practically in one step.
- This printing system object of the invention has an independent drying means in relation to each inkjet head, the drying means being located next to the respective inkjet heads, with an equal distance between each of the means. drying and the corresponding inkjet heads; using a means of drying whose action in the time of action on the inks only produces a partial drying of the same, leaving them in a gelled state.
- This system with partial drying of each ink practically at the same time of its application also allows printing at low speeds of up to 15 meters per minute, obtaining optimum quality; which is very useful, since in many applications, where the printing process is in line with other processes (sanding, finishing, etc.) slower, it allows not having to introduce acceleration / deceleration tables to the line, making it more Cut and save physical space.
- Figure 1 shows a conventional printing scheme by inkjet, by scanning.
- Figure 2 is a conventional inkjet printing scheme, in continuous, without drying means.
- Figure 3 is a conventional inkjet printing scheme, in continuous, with drying between the application of the different colors.
- Figure 4 is a printing scheme according to the system object of the invention.
- Figure 5 is a diagram of the result of two consecutive ink applications, with total drying of the first ink before the application of the second ink.
- Figure 6 is a schematic of the result of two consecutive ink applications, with the first ink partially dry when the second ink is applied.
- Figure 7 shows a diagram of the arrangement of two inkjet heads with a common drying medium and the result of the size of the ink drops after dried
- Figure 8 shows a diagram of the arrangement of two inkjet heads with respective independent drying means and the result of the size of the ink drops after drying.
- Figure 9 shows a graph of the expansion in microns of a drop of ink as a function of the time in seconds that elapses between the drop of the ink drop in its application and the partial drying thereof.
- the object of the invention relates to an inkjet printing system, for application primarily in continuous printing, such as that of Figure 2, in which the injection of the basic colors (C, M, Y, K), that is to say cyan, magenta, yellow and black, it is carried out by means of groups of independent heads (1) arranged to the triplet, with which the width of the surface (2) to be printed is covered, the printing being carried out with the fixed heads (1) and longitudinal displacement of the surface (2) below them; although the application can also be extensive for scanning printing, such as that of figure 1, in which the injection of the basic colors (C, M, Y, K), is carried out by means of a group of heads (3) that are they move together transversely to the surface (2) to be printed, in successive passes that are combined with partial displacements of the surface (2) in the longitudinal direction.
- the injection of the basic colors (C, M, Y, K) that is to say cyan, magenta, yellow and black
- each drop of the inks that are applied in the printing processes increases progressively in size as a function of the time that elapses from the projection until the ink dries, which results in a dispersion of said drops of the inks on the printing surface, which makes the colors fade to the detriment of the quality of the prints.
- drying means (4) between the application of the different basic colors (C, M, Y, K) in continuous printing, as seen in figure 3.
- the inks that are applied by a head (1) of a first group of heads (1) and by another head (1) of a second group of heads (1) arranged to the three-leg with respect to the first group are dried by means of drying (4), the first one at a distance (a) from the application projection and the second at a distance (b) from the application projection, whereby the dispersion of the drops (10) of the first ink and the drops (1 1 ) of the second ink, is different, said drops (10) and (1 1) resulting from one and another ink of different sizes in the printing on the surface (2) being printed, so that contrasts are different from the color in the print strips that correspond to the heads (1) of the first group and those that correspond to the heads (1) of the second group.
- drying means (5) are arranged individually in relation to each of the injection heads (1), being located of each means drying (5) next to the respective injection head (1) and with all drying means (5) at the same distance from the corresponding injection heads (1), so that the injection of each ink and its drying , they occur practically at the same time.
- the drying means (5) that are used to dry the inks in relation to each injection head (1), are chosen so that they do not dry the inks completely, since this can cause a rejection effect of the ink that is injected onto another previously applied, so it is necessary to only partially dry the inks, until they are gelled.
- Figure 6 shows the result of the application of an ink (8) on another ink (9) previously applied and dried only partially, where the ink (8) that is applied on it is absorbed by the ink (9) partially dried from the previous application, resulting in a uniform impression.
- the application of the printing system according to the invention is provided with the use of a set of UV-curable inkjet inks, using at least one cyan injection ink (C), a magenta injection ink (M), a yellow inkjet ink (Y) and a black inkjet ink (K), each with a corresponding UV-LED partial drying lamp, obtaining a four-color final image composed of the four basic colors (C, M, Y, K) in subtractive mode.
- C cyan injection ink
- M magenta injection ink
- Y yellow inkjet ink
- K black inkjet ink
- UV-LED lamps of 2 w / cm power and a wavelength of about 300 nm.
- a partial drying of the inks is achieved, in a gelled state, which allows printing without the rejection effect of the inks deposited on other previously applied ones.
- powers of 7 w / cm, in the range of 300 nm wavelength are insufficient to fully dry the ultraviolet drying inks with mercury lamps, whose power range it is in the order of 120 w / cm, with a wavelength of the order of 500 nm.
- the described printing system which corresponds to the object of the invention, is also capable of being used with the inks of the basic colors (C, M, Y, K) of injection printing and expansion with additional inks, for example white, increasing the range of resulting colors.
