How to glue the images

How to prevent bubbling.

Bubbles are caused when the glue dries too quickly in spots creating a pocket of air and does not adhere to the surface. This problem happens specially when working with larger images.

  • First thin the glue with water, then apply glue to sections.
  • Wet the paper first to help the glue absorb into the paper; This slightly "breaks down" the fibers in the paper to allow the glue to absorb (the paper becomes a little more fragile and must be handled carefully).
Other way to get rid of bubbles is by lancing the bubble with an exacto knife and reapplying glue.
  • Make one incision just large enough to be able to insert some glue
  • Use the brayer to flatten until the "seam" is not visible.
  • Keep the brayer clean otherwise to avoid attracting grainy particles which can tear or mark the paper.
  • Don't to use too much glue, this will cause the paper to tear and will clog the brayer with glue, and will lift some area of the image. Too much will also not allow the paper to lay flat and it will become difficult to work with.
  • Apply the glue evenly and quickly if using a large image.
Keep your hands clean by keeping a wet cloth or paper towel and a bowl of fresh water nearby and constantly wipe your hands. Not only will your fingers stick to the paper and cause tears but you are also more likely to pick up dirt.
  • When applying the paper, use a damp cloth starting in the center and working towards the edges.
  • Push out the excess glue. Once you are satisfied, seal the edges.
  • Use your thumbnail or a popsicle stick to rub over the edges firmly but not enough to tear.
  • Pay special attention to the edges making sure they do not lift.

All of these techniques take a little practice but any problems can usually be solved.
