I have created some screen printed images on two papers, Southbank Smooth and Lambeth Cartridge and some on clear plastic sheeting of an unknown make, all printed fine using standard acrylic screen inks. I have then gone on to laser cut and laser engrave these samples. The pastic worked to a suitable quality however this unknown material could differ from my inteded material Perspex, it is known Persex lasercuts very well, however the samples when cut created fumes which breached H&S regs, engaving was fine. The final result are positive and I shall move forward with this material.
