In printing tests or real jobs it is pretty much impossible to tell just what percentages and where they are in the curves other than they appear to peak around 30%. You can control them a little by how you build you black generation in your profile, but really all you doing is controlling black...
The 300 and 500 are not that bad if you do you own profile creation with a 3-party solution. Sure there are some ink limiting issues (more so with the 300 series) you have to work around and no control over the light ink curves other than printing without the light inks. And also as I am sure...
That is exactly what I asked, but you still won't tell, or don't know enough to be able to tell me. The only way you can be sure that no light inks are used even at 100% of Cyan or Magenta is to use CMYK Mode.
So with 500s to put more optimizer on the media HP will now use 2 optimizer heads...
"not much use during the print" Your lack of understanding is amazing. As you say your not sure where the ink splits/curves are for the light inks so you don't know how much light inks are used in say the 70% to 100% range in CMYKcm mode.
I never suggested the operator could deactivate one OP...
I just checked it on the printer creating a new media substrate and your right. Not sure I could see why I would want to use lc/lm with 4 pass, but hey if it works for you.
You don't seem to have much real world experience with these printers as you can't explain what you consider higher number of passes of if full color means CMYKcm or CMYK. If using CMYKcm then you statement in your first sentence makes no sense given what HP has said about the long run...
This is an issue caused by having only one lc/lm print head. You can't run 4 pass and use lc/lm inks, so no you would not see this color consistency problem.
Also the long run consistency setting as told to me by an HP representative only affects the the temp and power of the lc/lm printhead.
Forward comes in 60'. I never had any plasticizer problem with it and it's tear and tinsel strength specs are better then Key. Also not sure Key isn't the same thing as the Ultraflex junk.
Do you have the latest firmware on your printers? Seems to me there were some firmware that made the sensors for rail cleaning way to sensitive and were constantly giving this message. Something to check on.
You should be able to designate a percentage of K as Pure Primary or Black as Inkjet Black (depending on what your RIP calls it) with CM turned on.
Might be good to say what RIP and printer you are using.
So what device network ports today do not auto-switch? I haven't seen any for a long time now and I am sure your L310 port will auto-switch.
Nothing said here advocating connecting your printer to a router, only statement was about not needing crossover cables when connecting to a router.
They are right you should NOT be running a high bandwidth network connection through a router. Also set a static IP on the printer. If you have a router dishing out IP addresses connected to the switch be sure to reserve the IP of the printer in the router setup so that it does not try to assign...
Too much ink is being laid down for the passes and heat your running. Slow it up a little. You can try using inter-pass delay or setting your passes higher.
