ETP technology for ceramic tiles digital printing VIII ° Acimac annual meeting on technologies for ceramic tiles digital decoration Alberto Annovi 27/09/2016
Market demands The optimization of the ceramic digital process now goes in the direction of ensuring: - flexibility - productivity - short time-to-production - operating costs reduction TecnoFerrari is now introducing a new print technology in ceramic market in order to match these and future needs 2
An example of flexibility limitation Effect inks (e.g. Glossy, Matt, Luster, Glue , …) : - need specific printhead model with increased discharge - discharge or coverage limitations if using decoration heads - printheads installed for testing effect inks - customers need to «guess» printer configuration - different printhead model → different spare part 3
An example of productivity limitation Repeatability of same product at higher line speed: - waveform change or dpd limitations - different drop placement accuracy and «wood effect» - tonality change - printhead overspray and dripping 4
An example of time-to-production limitation Repeat existent production with a new printer: - differences in printhead dpd and drop size - difficulties in matching few «light» products quality - different inks for different printhead - different printhead resolution 5
Two examples of cost reduction limitation Printhead size vs ceramic tile size: - external printheads & electronics cost for using few mms - additional maintenance/recovery cost for these heads Dripping or spitting ink for keeping all nozzles active: - ink waste cost - belt cleaning device additional maintenance cost 6
Our innovative print technology Let’s see how our innovative print technology can give performance and reliability that are required for the latest generation print technologies moreover improve flexibility, productivity time-to-production and operating costs reduction 7
1. Our innovative print technology performances 8
2. Inside the innovation 9
3. Integration into a new printer 10
What we obtained Performance: 22 gr/sqm* laydown at 50 m/min @360 dpi Reliability: Robust metal plate, efficient and stable recirculation with dumpers Flexibility: Same head model can be used for high discharge effects Productivity: Long cleaning intervals, same quality at low and high speed Time-to-production: Resolution, drop size and same inks allow easy design repeatability Operating cost reduction: Reduced printheads number, no degassers, nozzles-active maintenance * Provided ink density is 1.3 gr/cm³ 11
Thank you This and further innovations for single & multi pass printing at 12
