    Posted by Jon Fields on April 18, 2005 at 8:40 pm

    When ever I letter magnetic sheet I tend to find more bubbles on this substrate than anything else.Even when i remove my application tape it seems to create bubbles that wasn’t present to start with..
    is it me..or do i need to prep it first..if so what with..and what is the best way to apply..I have noticed some suppliers selling solution that reduces bubbling once applied..has anyone tried it..

    many thanks

    Jon 😕

    Hi Jon, we use magnetic everyday and initially had this problem. we use fairy liquid in our water and find that this reduces this bubbles. especially on big surfaces. Andy

    Hi Guys
    I think if you do it dry you will get rid of you problems
    we do a regular flood coated yellow on to magnetic 2 1/2mtrs. x 610 dry then we put black text on top of that, if that doesn’t work I expect you just need to practice, if you have applied wet when you take your app tape off you will have bubbles because vinyl hasn’t adhered to mags unless you have either soaked your app tape or left it until completely dry
    usally over an hour (who has all this time too spare)

    hope this helps and doesn’t confuse you

    than anything..

    technnique trail and error, mag on table(work bench) enough vinyl and a bit extra no app tape stick one end with masking tape peel backing paper half way (it takes two peeps to do this) cut it off one person goes to far end other person stays at first end and squigees Peter usually uses a semi circle sweep I keep it from touching until he want’s it to and in the mean time I remove the rest of the backing(carring paper)
    If however I have to do it on my own that is completly differant if you want me to explain I will but I have proberbly put every one to sleep

    Jon, I always do them dry.

    I print a lot of vinyl and lay on magnetics, and had this problem in the early days. My solution was that I lay the sheet on a slab of steel to keep it flat. I secure the steel to the bench with doublesided tape so it does not move.

    Then I just lay it like any other sign, that has been premasked.

    I found the bubbles were cause by the sheet lifting slightly during application.

    I also apply it with a felt squeegee not a hard one. This seems to give a better result.

    Hope that helps
