It is an ideal method for junior students to do manual work.
Here are some tools.
Comparison of several paper effects
Monochrome paper
It is very thin, but it has poor water absorption and cannot be smudged, which is more similar to an oil-absorbing paper towel.
Kleenex tissue
Paper is thick, with granular protrusions, which absorbs water quickly, but it is easily broken.
cigarette paper
The water absorption is lower than cotton paper, thicker than cotton paper, the effect is worse than cotton paper, and the smudge effect is worse.
cotton paper
Fast water absorption, good smudge effect, the best effect, not easy to break.
nonwoven fabrics
Strong water absorption and good blooming effect, but it needs more dyes and is extremely difficult to dry.
Wet wipes
Good water absorption, but the color smudge is not obvious, and the color is more vivid.
Comparison of the Effects of Several Pigments
Poster coating
The color is bright and bright, and the blooming effect is obvious.
Watercolor painting
There is a sense of transparency, but the color is light and unclear, and the effect is not very good.
Color pen color
The color is bright, but the smudge is not obvious and the cost is high.
Pigment concentration comparison
Pigment should not be too thick, smudged or too thin, and everything smudged is water.
Pigment container
Flat-bottomed wide-mouth containers are better, because the poster color is easy to precipitate, it is easier to stir from time to time, and it should not be too narrow, such as disposable cups, because the paper will get stuck and there is no way to put it in for dyeing; But it should have a certain depth, not too shallow, such as a small disc.
Comparison of dyeing methods
Wet dyeing
When paper is wet-dyed, it breaks easily and does not spread, but it smudges quickly, but the color is not obvious.
Dry dyeing
Direct dyeing, bright color, easier to spread.
