Re: Removing fading/feathering from edge of image

I am having decent images come out on my mugs but need help solving one problem. The bottom of the mug on the image seems to have the colours fade out/feathered. I used to get this problem with the one end of the image by the handle and solved it by putting a tiny white border either end of the image. Do i need to put a tiny border along the top and bottom of the image too? Or do i need to tape on the image in a certain way? I would like to get the image to fully cover the mug from the lip to the bottom if this is possible.

my very first couple of mugs were full top to bottom prints but now I don't do it as that happened to me. I now leave a few mm blank top and bottom - as the rest of the mug is white I don't think this is a problem, you're never going to be able to print right up to the handle so a white 'border' top and bottom doesn't look odd.

try adjusting the clamp pressure so you can see the heater mat squeeze around the edges giving you better contact between the print and mug.

You would have to have a perfectly straight sided mug to guarantee full coverage otherwise cool spots will often occur. If I have to do a full side then I often put another piece of plain paper (or a thin silicon sheet) around the mug between the mug and mug press as this can help pressure issues.

This sounds like a press issue to me is it a cheap chinese job? some presses will do top to bottom no problem others esp the budget chinese jobs do have issues in printing all the way to the bottom id suggest leaving a border as you suggested

Well I personally do not think that fading detracts too much from the design (although it isnt right)

It would largely be the mug that causes the problem with the last 5mm or so of the base tapering inward. Not too many mugs have a good enough base to print full top to bottom so it becomes trial and error as to which you can do this with. Pressure placed on the mug needs to be slightly more as well if you are trying to get a full top to bottom print. Which mug are you using for the problem prints?

although id agree to a point with this its not the main cause , i have always used bms mugs i have a cheap press which i use for water bottles and a not so cheap press for my mugs which i get perfect top to bottom prints every time however if i use the cheap press i get the same issue as the picture in rennio's post same mugs differnt presses differnt results ergo its the press at fault

I would go for that as being the secondary cause in my book hence why I mentioned additional pressure to try and overcome the mug taper. If the mug isn't tapered at the base in the first place then there wouldn't be the problem to overcome. Whether you can overcome this is then down to the press. Just my opinion in having been through so many different mug options.

The straightest mug we have printed did in turn cause it's own printing issues so it is never straight forward. The way in which the kept it straight to the bottom was to place more ceramic into the base which then absorbed more heat than the rest of the body leaving it pale. Many different scenarios occur with different mug and press combos. Flaming is largely down to the mug.
