ABSTRACT:
A silkscreen printing machine having a large printing table and a stencil related thereto stretched across said table, said machine being provided with means for moving a squeegee relative to said stencil and for pressing printing ink through the stencil into a material to be printed upon placed on said table. During a printing sequence, and at least during the first and latter stages of said sequence when the squeegee is pressed into abutment with the stencil and when the stencil, located parallel with the printing table is caused to sag by its own weight to an extent such that the stencil at other regions than the engagement point of the squeegee should abut the material or the printing table, the stencil is arranged to adopt an oblique position relative to the printing table such that the angle between said stencil and said table at said squeegee engagement point exceeds 0.degree., meaning that the stencil abuts solely the material at the said engagement point. The movement of the frame is controlled by a plurality of operating rods, whose actuation is dependent upon movement of the squeegee and its position along the stencil.
