hi stu
imagine you can still get them from roland etc

you can still print and cut with these on but as you say not do a sheet cut.

Thanks Derek

I will have a look on their website, hopefully it will stop the head-strikes I’ve been having recently.

[Derek Heron]

when are you getting the head strikes stu

[Stu Gardiner]

quite regularly they are only very small and it is usually towards the middle of the vinyl, I have noticed that the vinyl seems to raise slightly towards the center even though I have the vacuum on fully.

i normally see this at the start of print .
i get over this by making sure the vinyl is lying well past the eye
so its hanging vertically heaters set at 39 and a decent room temp
roll out vinyl behind and double check for alignment
i notice with cheaper vinyls temp can make it ripple .
i use md5 have tried others but md5 works well although price is creeping up

Expensive wee buggars! In My Sign and Digital book they only do the short ones…. £58=VAT 😮 so id imagine the longer ones to be a similar price.

Ive seen me rolling out some masking tape, attaching to the middle of the vinyl and letting the roll of masking tape hang of the end of the vinyl. But as said ive only experienced this problem at the very start of the print! And not very often at that!

Dont bother wasting your money on the clamps stu – they only really stop the head getting caught as it passes the outer edge of the media. They’ll make little or no difference to the centre of the media.

I get this when the temperature of the roll is lower than the pre-heater, its particularly bad at the moment as its cold outside. Try lowering the heaters say 5 degrees and see if that alleviates it.

The Arlon 4500 I use suffers exactly the same but find 40 degrees pre and post print works well when it starts to buckle. You can always shove a halogen heater in front it you find you have heavy print areas that arent drying as quickly as you’d like.
