whats the best way to go about backslitting the liner?

[David Rogers]

Do you mean like ‘crack-back’. (usually seen on commercial safety stickers). I get the feeling that that stuff has a pre-spilt liner before the adhesive vinyl is rolled with it.

if you mean slitting it so you can tape n the middle, then i usually lay it flat, face down, peel back the liner, cut it off, and re-lay it on with a couple of mm overlap, make sure the liner is bigger than the design and has the app tape on to keep it all in place (easy forgotten on a flood sheet !),

i have done it using a slit knife, but the problem is lifting the liner clear in the first place !

if anyone has a better idea, i’d be pleased to know too !

edit: been jumping in too quick today !! no idea on small stuff ! what he said above ! 😳

Hello David and Hugh, unfortunately not crack-back. It has to be plotted and then backslit.

With a new scalpel blade it’s quite easy, but I don’t really fancy doing a thousand or so with that degree of precision, or picking up and putting back down again!

I think it’s a bit too small for a snitty

Now this might sound a bit mad – but I’ve just given it a go.

Using your blade holder (set to the right depth – trila & error) & a straight edge score/cut the liner on the reverse.

IT WORKED…sort of.

Granted I did blow a couple of bits of pre-cut letters trying it.

Give it a go, nothing to lose but your sanity.

Richard,

Do you mean something like the backing slitter?
You can adjust the depth of the knife with this one, I use these for cutting the backing of (cold) laminate.

Hi
you can have a laser cut run across the backing sheet

A laser cut run???
Sounds interesting, can you give some explanation or links?

Thanks,
