TRANSFER-PAPER AND INK THEREFOR.

T 0 all whom it may concern.

Be 'it known that I, HERMAN KRUSE a citizen of the United States, residing at ersey City, in the county of Hudson and State of New Jersey, have invented certain new and useful Improvements Papers and Inks Therefor, of which the following is a specification.

My invention relates to improvements in transfer papers, and more particularly has reference to the ink to be applied thereon. Heretofore it has not been possible to ink these papers 1n a printing press owing to the stiff and hard character of the ink which does not transfer properly from the rolls and does not work as printing ink should do owin largely to the considerable amount of para fi in used in the manufacture of material.

According to a preferred embodiment of my invention I refer to mix about 54 arts by weight of mmeral oil-such as para n oil with about 45 parts by weight of stearin pitch also known as ink makers pitch, and

also about 43; parts by weight of paraffin wax. This forms the vehicle. I now prefer lbs. of this vehicle, about 20 lbs. of carbon or grindv the entire mixture on a printing ink mill and apply the ink thus made to the surface of the paper by a printing press. The
