Oracal 3651 – Which laminate

[Tim Knight]

Hi Doyle,
sorry for the late reply haven’t call in to the uksignboards for awhile
we use orajet 3651 on everything except vehicles
and clearcoat everything with the same media but in clear.
has been working very well for us using a Roland sc540 ecosol printer

for us prints the best and the vinyl is good value for money!

Regards

I use the 3651 a lot and as Tim says, just laminate it with the 3651 clear. It makes it a bit thick for some applications tho, so I also use the 200 laminate. Only use the 215 for 3751.

Cheers
Shane

Thanks for the replies. I had a big problem with the 3651 the other day. I left the printer unattended while it was printing graphics approx. 5 feet long. When I returned, to my horror the machine was jammed, and I had a streak in my print about 2 inches long by 1 inch wide, which I assume was a head strike (possibly multiple head strikes). What happened was the plastic rollers that insert into the core of the media did not fit tight enough and while printing, one actually fell out, causing the media to fall to the metal rollers on that side. The display said FEED MOTOR ERROR, POWER OFF.

The plastic rollers fit very snug in the roland media, but seem very loose in the oracal. I put the vinyl away and haven’t even looked at it since and I returned to using the GCVP Roland stuff. Another problem I have had, when using the profiles and settings provided by oracal, it seems to heat the material too much causing it to buckle and nearly hit the head sometimes, and the colors are very dull looking compared to the results using the roland media/profiles. Oracal suggests bi-cubic interpolation and CMYK v – W pass printing, could this be the problem? Am I the only one having these problems? Thanks in advance.

Sorry, one more thing. I have been told by suppliers that it is ok to use cast laminates on calendered prints, even though I have read several times that you should always laminate with the same type of media that it is applied to. I know not to use a calendered lam. on a cast print, but is this true when using cast lam on calendered print? I was told that the cast is forgiving enough to use on a media that will shrink. Thanks everyone!

Throw away the Roland media holders and get some summa ones. The summa ones will hold well on any of the cores as they expand inside the core. 1 or 2 messed up jobs will more than pay for the media holders.

Personally I very rairly use the media holders. Im just lazy and they are to much trouble to put on… 🙂 It works fine as long as you keep the metal rollers clean.

I am the same. had problems with the roland media rollers the 1st time I used them. Threw them in a box, never used them since.

A cast laminate on a calendered vinyl is a no no, for anything long term. They have different shrinkage rates, so will buckle if in the wrong environment.

I have used a cast laminate on a calandered print, but only for short term use. Cast lam is dearer than cal lam anyway, so it would be a dearer option as well.

code :thats what the white collars on the rollers are for.

mucked that up

Thanks for the advice. I wasn’t sure if it was a no-no placing the media right on the metal rollers, maybe the motor has to work harder to feed the media?

Chris, I use the collars on the rollers, the media holder fell out of the core at the top, and the bottom was still against the collar. Thanks!
