Abstract

Abstract A method of correcting a mistyped carbonless Business Form Set. The set consisting of two or more collated sheets of paper that when typed, printed or pressure applied will produce copy of the indicia applied without the use of carbon paper or other visible form of color. A set consisting of two or more sheets of such paper, the face top sheet known as the original copy generally doesn''t carry any coating whatsoever. The back of this original copy has a coating that is colorless referred to as coating composition A. This top sheet is placed collated on top of a copy sheet that has a coating on both sides of the paper. The face of this copy sheet has a colorless coating B thereon different from coating A. The back of this copy sheet is coated with a coating A referred to before. By adding multiple sheets of this copy sheet there is obtained a 2-3-4 etc. part set. When the pressure of a typewriter key, printing press, pencil or like pressure is made the desired indicia is made on all copies. The method of correction is then carried on by using opaquing sheets having a bottom coat of pressure transferable pigmented coating and provided with a tacky face top coating, by suitable placing the opaquing sheet to opaque any errors and thereafter inserting an image transfer sheet having a transfer coating thereon corresponding in color to the final color attained by typed copy on the copy sheet or sheets and by the method of typing error again then typing correct indicia.
