Any EDGE expets out there??
Hi looking for some rapid advice / help
Spandex Tech don’t seem to want to pick-up..
The problem: When i use more than 2 foils, there is a very slight registration failure between colours. Consequently, if i do a CMYK print it’s a waste of time because the end result is at best ‘fuzzy’ as if camera shake is evident, at worse its in the bin!!
Anybody experienced this problem before?? any ideas on its cause / remedy??
I would imagine that it must be a software thing, unless there is a ‘clutch’ type arrangement between the colour foil and the vinyl.
if the foil moves ever so slightly after the vinyl or vice-versa i could imagine the same results then..
regards
Darryl

long shot, but have you tried Robert Horne S&D?

it is normal for the edge to not have perfect alignment between spot colurs. that is why you need to bleed and overlap at the design stage, but usually only needed for long runs, or small detail.
The other thing, are your cymk foils about equally used? if not this has been known to give the problem, that is, using a half used foil, with a new one.

I hope it’s OK to post another forum on here.
Normally I wouldn’t do this, but I actually know the guy who hosts this
(a fellow Pennsylvanian)
and I have even been to his shop.
And the forum is strictly to discuss the Edge.

Cheers for the quick replies guys..
Robert Horne S&D… Whats the S&D bit??
Peter, i may be misleading when i say CMYK! If i use a jpeg as a base, with text over this is where my problem is .
if i use spot colours i will assign those via the Omega programme, i don’t seem to have such a pronounced effect then..
does that make any more sense??

Love…..JillI have been trying to register there for over a week now.. :lol1: :lol1:
i fill the form, and the auto system tells me that my application is all good, but i’ll need to wait for an administrator to clear the account and send me a link that i have to reply to gain access…??

Tip one: cmyk foils must be of the same length, main reason for misregistration.
Tip two: ensure that there is no glue build up on the sprockets.
Tip three: how old is your edge? If fairly old (4/5 years or more) it could be the clutch.
Choke & spread and bleed are usually a must on the edge, but obviously these are for spot colours, not for cmyk (apart from bleed).

There’s been a fair amount of spamming & other types of abuse on the above mentioned website, hence why the registration process is so long at the mo, script kiddies were autoregistering & posting various links to porn etc.

Cheers for the above tips Goez. i use 45m refills and when in cmyk mode there always used at about the same rate, so the tension should be about the same.
i clean the sprockets as and when i think i need to 😮 , which may not be soon enough 😳
i have spoken with the Techies at Spandex and apart from the choke/spread ‘trick’ the problem could be alleviated by the
re-alignment of the head!!
According to the guy up there, when the edge prints it uses a fair amount of friction and that same friction could pull the head slightly off square.I’ll have a shot at the choke /spread idea because at the moment i have
14,000 decals waiting 🙄 🙄
cheers

No probs Darryl.
Good luck!

I have looked at this problem many times and have found that it is usually the first foil printed that doesn’t align with the rest. We haven’t been able to ascertain the cause for this but some have mentioned tension in the roll of vinyl which when processed through the edge is heated and stretched slightly so that by the time the second foil is printed the length of the piece has changed slightly.
A trick we have used in the past on fine detail work is to print an additional spot colour block at the end of the design and ensure this is the first foil. This way the roll is processed on a sacrificial foil and alignment of the following foils is correct. Wasn’t 100% but did make a difference for us.
Hope it helps.

Sounds good Colin….
so i have my design within a cut box…
where do i put the sacrificial block?? after every repeat column and outside the cut box obviously..OR at the end of the run??
i would think the first. if it was the latter i could pre shuffle..??

The less you can get away with the better for economys sake but at least one right at the end of the design so that the full amount is wound out. I use a thin block across the width and occasionally repeat this down the design at regular intervals.
Its a bit trial and error and factors like room temperature and humidity also play a part in the stretching, but it does give you something to try.

i’ll give it a try Colin.. 🙂

Hi Darryl,
not sure if this helps but we use the Gerber edge 2 but set it to edge 1 mode and get better results, also do as many repeats in omega as GA plot will see this as one shape,
this way you can eliminate some of the alignment problems, i believe that in GA plot repeats can run out by .01mm per repeat in the X and Y, so on small labels say 20 up this could be 2mm out.
Also where possible we turn overprints on so you don’t get the little white gap sometimes seen. -

Colin .. i think you’re onto something there 😀
i have just amended the design
i was using 3 colours – (black plus 2 to make 1)i reated the design to 100 units and put a 2mm vertical bar of black with no cuts across the 297mm width. i then told the software to repeat 5 times giving me 500 units total along 6.5 mtrs
RESULTS ARE MARKEDLY BETTER :lol1:
Kat…i did think of that but it takes for ever and a day.. and i have got 15000 to do in total which is roughly 195 mtrs or 4 rolls of base vinyl..
i do use edge 1 when printing onto clear as it tends to ‘ghost’ at the faster speed..
