Abstract

Procedure for printing images on the edges of the books in which the edge of the book on which an image is to be printed is prepared with opening and matched of the pore and application of mordant, which has previously been printed specularly on a sheet waterproof, and solvent is applied to the edge of the book and then place the printed sheet on the edge by pressing on it.

PROCEDURE FOR THE PRINTING OF IMAGES ON BOOKS

OBJECT OF THE INVENTION

The object of the present invention is to present a new procedure for printing images on book edges.

This new procedure has special application in the publishing and printing sector and especially in the binding sector.

BACKGROUND OF THE INVENTION

To date, there are different ways of decorating the edges of the books, including the manual painting of the edges of the book or the gold leaf lining of the edge of the book.

Printing techniques are also known in which the image printed on a sheet is transferred onto other surfaces using solvents, in these cases what is done is that the solvent is applied to the face of the sheet that is not printed and the solvent passes through the sheet by dragging the inks on it and printing the surface.

These techniques have the problem that print resolution is lost since the solvent must pass through the entire sheet and they are also not applicable on book edges since the inks excessively impregnate the edges of the pages of the book, being inserted between them and gluing some pages with others.

Other existing antecedents are for example the patent JP2007030294A that refers to a printing of a brochure of an image, from a film with the mirror image, which is transferred to the surface to be printed from pressure and heat, applied by a roller. This document only mentions the printing of the mirror image on a film and then the transfer to another surface is made by pressure and is far from the object of the present invention.

Patent CN102501671A refers to the printing on the edge of a book, starting from printing the image on a support, preheating a plate, placing the sheet on the edge to be printed, and transferring the image from of the application of pressure and temperature on the edge of the book.

Patent US2003107164A1 describes a printing procedure on book edges, where there is a pre-printing preparation, and where solvents are used to optimize the quality of the image to be printed. However, it does not disclose the printing technique used.

DESCRIPTION OF THE INVENTION

This new procedure for printing images on the edges of books essentially consists of preparing the edge of the book on which to print an image that has previously been specularly printed on a waterproof sheet.

The preparation of the edge of the book is done by leveling the cuts, pressing the book, opening and leveling the pore of the cutting surface, applying mordant to facilitate adherence and fixing of the inks.

The image to be transferred has been printed, specularly, on a waterproof sheet.

Once the sheet is printed, solvent is applied to the edge of the book and the printed sheet is placed with the printed side glued on the edge of the book impregnated with solvent and uniform pressure is applied.

The solvent on the edge of the book dissolves the inks printed on the waterproof sheet that are transferred to the edge of the book, leaving the edge of the book printed with the image that was printed on the waterproof sheet.

DESCRIPTION OF THE DRAWINGS

To complement the description that is being made, and in order to help a better understanding of the characteristics of the invention, the present descriptive memory is attached, as an integral part thereof, to a series of figures in which, for illustrative purposes and not limiting, the following has been represented:

- Figure 1: View of a photo from a book with the printed edge.

- Figure 2: View of a photo from the same open book.

PREFERRED EMBODIMENT OF THE INVENTION

The procedure for printing images on book edges is preferably carried out with the following phases:

Preparation of the edges of the book where the image will be printed with the phases:

- matching the cuts of the book to avoid irregularities,

- introduction of the book in the press so that the pages are together, - opening and equalization of the pore of the surface of the cut of the book to which the image is to be transferred,

- application of mordant on the surface of the cut of the book.

Printing on a waterproof sheet of the mirror image to be transferred to the edge of the book,

Solvent application on the cut surface of the book on which the image is to be transferred,

Placing the waterproof sheet on the surface of the book cut where the solvent has been applied and with the side of the printed image facing the book cut and pressing the sheet on the book cut, thus the solvent applied to the edge of the book it dissolves the inks of the sheet that are transferred to the edge of the book.

Separated and removed the waterproof sheet from the surface of the cut of the book on which the image of the sheet has been printed.

The procedure may have additional stages so that, once the image transfer process is finished, optionally, the book can be waxed or satinized.

Likewise, alternatively, the printing phase on an impermeable sheet of the image to be transferred can be carried out firstly, before preparing the edges of the book, but always before applying the solvent on the edge of the already prepared book to prevent it from evaporate while printing the image on the sheet.

Finally, it should be noted that the phase of applying mordant to the surface of the book edge in its preparation can be eliminated in some cases depending on the porosity of the paper.

Any reference to the printing of images is also applicable to a text that you want to print on the edge of the book.

Once the nature of the present invention has been sufficiently described, as well as a way of putting it into practice, it only remains to add that said invention may suffer certain variations in form and materials, as long as said alterations do not substantially vary the characteristics claimed. then.
