Description

Procédé pour le séchage d'impressions.
Les couleurs pour l'obtention d'impressions mono et poly- chromes se composent de colorants qui sont mélangés à des huiles siccatives, l'huile de lin par exemple, auxquelles on ajoute le cas échéant des agents pour accélérer le séchage. Ces additions nécessitent pour le séchage des couleurs ordinaires un temps relativement long de sorte que pour l'impression mono- chrome on doit intercaler des feuilles entre les impressions venant de la presse à imprimer, tandis que pour l'impression
<Desc/Clms Page number 2>
en plusieurs couleurs; on doit attendre le séchage complet de l'impression effectué en une couleur avant que l'impres- sion avec la couleur suivante puisse avoir lieu.
Les procédés d'impression connus jusqu'ici présentent donc l'inconvénient d'une grande perte de temps et d'un prix de revient relativement élevé ; cet inconvénient est supprimé par la présente invention en ce sens qu'elle a pour but d'ef- fectuer le séchage directement après chaque phase d'impres- sion, dans le temps le plus court, grâce à quoi l'intercala- tion de feuilles devient superflu et lors d'impressions en plusieurs couleurs, le tirage avec la couleur suivante peut avoir lieu immédiatement après l'impression précédente
Ce but est atteint conformément à l'invention, en ce sens que l'impression est soumise à l'action de rayons agissant chimiquement, par exemple, aux rayons d'une lampe à quarz.
Grâce aux rayons traversant la couche colorée ]le séchage a lieu dans un espace de quelques minutes grâce à l'accéléra... tion du procédé d'oxydation.
La source de lumière produisant les rayons agissant chi- miquement peut être placée à un endroit convenable, soit au point de sortie de la feuille imprimée hors de la machine, soit derrière celui-ci. Pour l'impression en plusieurs cou- leurs, les impressions avec toutes les couleurs peuvent avoir lieu successivement sur une machine unique, par exemple, sur une presse à imprimer rotative, lorsque l'on prévoit entre les divers points d'impression des différentes couleurs un ou plusieurs corps produisant un rayonnement.
Dans ce cas il n'est pas nécessaire de diminuer la vi- tesse de rotation de la presse, lorsque l'on prévoit un che- min suffisamment long pour le papier recevant l'impression, ce qui permet de disposer un ou plusieurs corps produisant un rayonnement, de telle manière que la première impression est complètement séchée'lorsque l'endroit pour la seconde

impression est atteint.

Process for drying prints.
The colors for obtaining mono and polychrome prints consist of dyes which are mixed with drying oils, for example linseed oil, to which agents are added if necessary to accelerate the drying. These additions require a relatively long time for the drying of ordinary colors, so that for monochrome printing one has to insert sheets between the prints coming from the printing press, while for printing
<Desc / Clms Page number 2>
in several colors; one must wait for the print made in one color to dry completely before printing with the next color can take place.
The printing methods known hitherto therefore have the drawback of a great waste of time and of a relatively high cost price; this drawback is eliminated by the present invention in that its object is to carry out the drying directly after each printing phase, in the shortest time, whereby the intercalation of sheets becomes superfluous and when printing in multiple colors, printing with the next color can take place immediately after the previous printing
This object is achieved in accordance with the invention, in that the printing is subjected to the action of rays acting chemically, for example, to the rays of a quarz lamp.
Thanks to the rays passing through the colored layer, drying takes place in a matter of minutes thanks to the acceleration of the oxidation process.
The light source producing the chemically acting rays may be placed in a suitable location, either at the point of exit of the printed sheet from the machine or behind it. For printing in several colors, the prints with all the colors can take place successively on a single machine, for example, on a rotary printing press, when provision is made between the various printing points of the different colors. one or more radiation producing bodies.
In this case, it is not necessary to reduce the speed of rotation of the press, when a sufficiently long path is provided for the paper receiving the printing, which makes it possible to have one or more bodies producing. radiation, such that the first impression is completely dried 'when the place for the second

printing is achieved.
