I have learned a lot from this forum.
We have run a HP45500 for the past 4 years and are now ready to invest in a true flatbed. We spent a lot of time with David and crew at the CET booth in Vegas last week. The machine that best fits our current needs in terms of a speed and quality combination is the X-Press 500 with the Spectra heads. I know there are many folks who are fans of the Ricoh head machine.....I was wondering if there are any problems related to the Spectra heads.
Our HP has two sets of heads, so we easily mask when a nozzle or two goes out. Is missing jets a problem with the CET Spectra head machine? How does that affect image quality? We are looking at the X-Press 500 with the single set of CMYKlclm+W heads.
Your assistance is greatly appreciated.

Hi Doug.
Right now, I only see Durst doing a great with speatra head for UV printing, they also so with Richo as well.
The weakness on UV printing with speatra head is you will see some nozzle lines, not as smooth as you want. As spectra polaris basic resolution is 100 per module, each module have two lines, and each polaris print head have two pieces, 4 lines, total physical resolution is 200dpi, print width is about 64.89mm, that will affect the quality expecially when you print with low passes.
May you can consider the Konica head 512/14pl. That is the most popular print head in this field now, with its stable, quality and easy maintenance.
and its upgrade to 1024/6pl. a great quality output.
Or you can also check the Toshiba head, Oce Arizona printer. Quality and speed as well .
