8 Claims. (01. 101-416) This invention relates to a method of printing drawing, the ink solvent remains liquid in the and more particularly to a method of setting press which is operated at ordinary room temink on printed material. perature (20 to 25 C.) so that substantially no My method contemplates the use of anink condrying of the ink occurs on the rollers or plates taining a solvent whose vapors are inflammable of the press. As the web passes over the heated and includes the step of igniting and completely roll, it israised to a temperature at which the or partially burning the vapor of the solvent in solvent vaporizes rapidly. Solvent vapor, therethe ink after the ink has been printed on paper fore, rises from the web at and beyond the heat or other material. The method has the advanroll and the air overlying the web becomes mixed 10' tage of causing a more rapid setting of ink than with the vapor. The vapor is ignited by the gas 10 has heretofore been obtainable, and also of flames from the burners A-, and being mixed with chemically destroying thesolvent. in the ink so air the vapor burns very rapidly or flashes. that it cannot resoften the ink after it has been The vapor flashes so rapidly that the flame of set. Furthermore, I have discovered that ignithe burning vapor extends only a short distance tion and burning of the ink vapor may be carried along the web. Any flame which may extend as 15 out without scorching or burning combustible far as the rewind roll is snufiedout as the web material such as paper to which the ink has been is wound up on this roll. applied.

In carrying out my method with such an ink 1. In a method of printing which comprises 5 and with apparatus such as that indicated in the applying to a sheet a printing ink containing a 55 volatilizable liquid whose vapor is inflammable and thereafter vaporizing said liquid in the ink on the sheet, the step which consists in igniting the vapor of said liquid as it emerges from the ink on the sheet so that the vapor is at least partially burned in immediate proximity to the sheet.
2. The method of printing which comprises applying to a combustible sheet an ink containing a volatilizable and inflammable liquid, and thereafter volatilizing said liquid while the sheet is exposed to the air so that the vapor emerging from the ink on the sheet becomes mixed with the air overlying the sheet, and flashing said mixture in the immediate proximity of the sheet.
3. The method of setting a printing ink containing a volatile and combustible substance which comprises volatilizing, igniting and par-.

6. In the method of applying to a sheet a contains a thickening agent dissolved in a volatilizable and inflammable solvent liquid which is stable at ordinary press room temperatures and thereafter vaporizing said solvent liquid in the ink on the sheet, the step which comprises ignitsaid solvent as it emerges from the ink on the sheet, so that the vapor is at least immediate proximity to the sheet.
7. The method of printing which comprises applying to a combustible sheet an ink whose printing which comprises vehicle containsa thickening agent dissolved in a volatilizable and inflammable solvent liquid which is stable at ordinary press room temperatures, and thereafter volatilizing said solvent liquid while the sheet is exposed to the air so that the vapor emerging from the ink on the sheet becomes mixed with the air overlying the sheet, and flashing said mixture.
8. The method of printing which comprises printing ink whose vehicle applying to a traveling web an ink whose vehicle 2 contains a thickening agent dissolved in a volav tilizable, inflammable solvent liquid which is stable at ordinary press room temperatures, heating the web at a point of its travel to volatilize said solvent liquid and igniting the vapor as it 30 emerges from the ink on the web.
