![]() You can get etching needles from various manufacturers. It is the main tool used for lines and hatching and stippling. If you are getting just one tool for drypoint, this would be the one. Also you'll need to be careful not to accidentally cut through the plastic.ģ - Double ended etching needle (or regular etching needle): It is good for making extra large lines though, much deeper and wider than you can get with an etching needle. The line was rather hard to control, so the tool won't be good for precision areas. scrapes) are created when etching with this. The first thing I noticed was how much burr (i.e. I didn't have a graver, so I used my Spitstiker instead. Wood engraving tools such as Spitstiker and gravers are sometimes used for Intaglio printing, especially on copper plates. This is used to remove excessive burrs created when using engraving tools (such as the spitstiker) to etch a line on the plastic plate. Though if you are desperate to remove an accidental mark (like I was), it is an option. I wouldn't count on this as an erasing tool for plastic. I can't vouch for this as I have only 'erased' a small mistake. Though too much burnishing could result in a gray patch. The mark won't be gone completely but it could be lighten. Mistakes can be 'erased' with a burnisher to a certain extent. And then on top of this gray background, I can add more lines to build the design. I needed to constrain the gray to the bird's breast, so I used a frisket film to mask the areas which should not have the gray. I haven't tried this with Tetrapak, but I suspect it won't work so well on Tetrapak as the paper will probably get too mangled by this. I found you could achieve various shades of gray by roughening up the plastic with sandpaper or wire brush. ![]() This may not work so well is the black area were larger. To get the beak really dark, I found I had to do a very dense hatching with the etching needle to achieve a satisfactory black. This course will follow the KBA-NotaSys philosophy and approach to digital engraving using the CTiP process.Unlike Tetrapak, where you could peel off selected areas to reveal the cardboard underlayer for flat black zones, with plastic you only have lines or grays. Finally, the students will receive information and training on the latest developments in advanced intaglio proofing techniques and processes in order to ensure consistency of the printed results until the final production. The subject of integrating other security features with intaglio designs will also be addressed by experts in this field. Specific attention will be given to the importance of developing appropriate ink retaining structures within engraving profiles to achieve the desired printed result. The digital engravaing workflow is presented and explained and students have the opportunity to elaborate an engraving from sketch-work through to a 2D and finally a 3D intaglio engraving. The Digital Intaglio Engraving Course (Part1) focuses on the tools and technology used to digitally create intaglio engravings.
