Definitions
- the invention relates to a method for the application of a protective light-transmitting coating on a toner image formed on a substrate which is obtained by charging up a photoconductive substrate, image-wise discharging this by exposure and its development by means of pigmented toner and the subsequent transfer of the toner image obtained to a receptor substrate.
- the present invention provides a solution for this problem.
- a second toner image is formed with a protective light-transmitting toner, this second toner image being registered with the first image on the receptor substrate, and subsequently fixed.
- protective toner is applied exclusively to the substrate where pigmented toner is present so that the surface portions of the substrate not provided with an image retain their original surface structure.
- the invention can be used especially where, using known electrophotographic techniques a proof print is formed from a colour print, using a number of colour separations obtained from an original.
- the operation of applying the protective toner can be undertaken precisely as many times as there are colour separations, using on each occasion another colour separation, but it is also possible to form the protective toner image starting with an exposure of the photoconductive coating via all the colour separations employed during image formation and brought into registration therewith.
- Figure 1a a illustrates schematically a substrate 1 which is image-wise covered with toner of different colour; toner of the first colour is indicated by the toner sections 2 shown as solidly filled, and toner of the second colour is indicated by toner sections 3 which are shown thatched.
- the toner images are obtained in the conventional manner starting from respectively the light-transmitting colour separations 4 and 5; toner image 2 is obtained after exposure via colour separation 4 and subsequent development with toner 2, and toner image 3 after exposure via colour separation 5 and development with toner 3. Naturally there are also locations where toner images of the two different colours are placed one on top of the other, and locations where there is no toner present at all.
- the image obtained in this manner is covered with a transparent, non-pigmented protective toner only where pigmented toner is present.
- a transparent, non-pigmented protective toner only where pigmented toner is present.
- Figure 1f indicates that it is also possible to apply the protective toner in a single operation. Then a toner image 9 is formed using all the colour separations 4, 5 employed during the formation of the respective partial images, these being registered one above the other, and via which the photoconductive covering 10 to be employed is exposed. The toner image obtained after exposure and development with protective toner as shown in Figure 1f is then registered on the image 2, 3 which is to be protected. Figure 1g shows the result finally obtained.
