Silver ink in SP300

Post by deep six » Wed May 03, 2017 12:58 pm

OK. This may seem a stupid question but please humor me. I have an SP300 printer which I use to print motorcycle decals.
Lots of my decals have a silver element. My printer doesn't have silver print capability so up to now I have been cutting out a piece of silver vinyl and sticking it in place of where the silver would be printed.
This is very time consuming and prone to misalignment which results in wasted decals ending up in the reject pile.

So thinking to myself, what would be wrong with taking out the black cartridge and replacing it with an ecosol max 2 silver cartridge.
I know what you are thinking, the machine wont recognise the silver cartridge, thought of that, I use an old back cart case with silver ink inside, so how am I going to tell the machine to print silver, Where I want silver I just use a black fill, what if I need black? I just make black by dialing up full cyan, full magenta, and full yellow.

I understand the ink will need to be primed through the system and flushed out after use. I intend to do a full run of all my silver decals and then replace the black cartridge and flush through..

I know I should just go out and buy a new machine that prints silver but my service guy tells me he is forever servicing these machines as the silver gives problems and clogs the print head unless the machine is used constantly, So that kills that idea as I only print two or 3 times a week.

Ok, please let me know your thoughts.

Cheers

Ric

SP have no circulation so you would need to flush the whole line of ink every time you want to use it.

It'd be a train wreck of a project as is.

As mrtn says, its the same reason why you cannot use white ink in a machine not designed for it, the ink settles in the carts due to being metallic (or white, which primarily uses titanium dioxide iirc). It also settles in the lines, seperating out both components.
