And I noticed that apparently I replied before reading an entire page of posts... oh well. One thing I've noticed about the HP Latex printers is that most profiles are made for either Onyx or Caldera. If you're using anything else, you're pretty much stuck with the canned profiles it comes...

The water-based DesignJet printers had major issues with feed accuracy causing film positives to become distorted. The L25500 is built on the same type of chassis as the older DesignJets, and on top of it, the heaters induce MAJOR distortion in many materials. If you're doing single plate...

Well, to throw my own $0.02 in, after all this... Computers are tools. (Most) users are tools. :P The choice of hardware doesn't really matter any more, since the only PC platform now is x86-64. For most purposes, the software doesn't really matter either. You can get work done with just...

The bad thing about Windows studies is that a great many of them are sponsored by Microsoft. And they Have An Agenda. If you want real-world results, look no further than Pwn2Own.

There are technical merits to OSX from a security standpoint. It's not necessarily harder to write a virus for OSX than it is for windows -- but it IS harder to find a security flaw for your virus (or, in the case of the Register article, a trojan would be more accurate) to exploit. Linux also...

As far as the DX5 dampers with the valves, the only reason that the manufacturers (Epson, Mimaki and then Mutoh) moved to them was to prevent pressure-related dripping from the heads. If you use the old style dampers, you have to keep the system in equilibrium, in other words, the level of ink...

We're actually looking at a Kern laser. The 400W model will cut metal pretty quickly; aluminum is the PITA of laser cutting metals due to its reflectivity, so the Al cutting ability of a high-wattage CO2 laser is pretty low (something like 18ga sheet). Mild and stainless steel, however, are...

OP was asking if he could heat press to Sunbrella. Most heat transfer films require a setting temperature of about 325F, which is above the melting point of acrylic. Unless there are some low-temp transfer films for acrylic that I'm not aware of...

Well, let us know what you see at Shanghai. I'm sure you would be able to put together a report rivalling Dr. Hellmuth's FLAAR reports :D Having said that, single-pass 700 sf/hr with two DX5 heads strikes me as unrealistic given the nature of ink supply systems and the restrictions inherent in...

Keep in mind that acrylic (what Sunbrella is, if memory serves) will melt at the boiling point of water (212F). It catches fire around 550F. http://www.dynalabcorp.com/technical_info_acrylic.asp

Oh, I don't doubt that you can get more bang for your buck in China. However, all that capability is coming with the tradeoff being overall quality. You're going to experience more downtime due to random failures like bad solder joints, crimped cables, burned-out motors, and flaky (read...

If that other printer is running KM1024, or even KM512 heads, it can go as low as 4-6 picoliters; the DX5 goes down to 3.5 picoliters. Basically, if the printer is designed to use the heads well, you can easily print 4pt type with Konica heads. I have some samples printed on the new Jetrix...

It also depends on speed vs quality. The QS series uses fixed 15pl dot Seiko SPT-510 heads, while the newer GS series uses variable 12pl dot SPT-508 heads. As a result, the QS series quality (which looked excellent six years ago) is starting to look very grainy compared to output from newer...

Just FYI, that sort of damage suggests that the printer experienced a power surge or something similar. I would suggest either having the printer hooked up to an industrial-quality surge suppressor, or (less expensive) a UPS battery backup unit. Just make sure the UPS has enough juice to support...

Does the servo controller flash any error codes (e.g. E-0-7) when you get either a print line or encoder error message? It's possible that the magnetic encoder strip got nicked. Do the errors occur in a specific place, or does it just seem to happen at a random position?

That looks like something I'd expect to see in Tijuana...

There's a major issue to be aware of when working on the heads or dampers on any ValueJet. You do NOT need to loosen the screws securing the print head when merely replacing dampers; if you do, the head is spring-loaded and can pop out of position easily. I've seen many people try to replace...

The heads the Chinese are selling as solvent heads are actually Roland-packaged DX4s with the factory solvent manifolds. The water based DX4s are ripped out of Epson 10000 spare head carriages, which go for a bit less. (It used to be about $750 per carriage here in the US, or about $225 per...

My general feeling about HP, which I have had for quite a few years (and note that I work on a LX850 at my shop) is that they feel all end users (and techs, for that matter) are idiots. That's why their machines have such a high degree of automation. Automatic cleaning, a$$^H^H^H head wiping...

:ROFLMAO: ... can't breathe ... That was a good one, Artbot... Thanks. I needed that.
