Likely one of the main parts of picking Watercolor paper is the surface as this will either help you or upset you with your watercolor painting. Watercolor paper is partitioned into three classifications as indicated by the outer layer of the paper: Harsh, Hot-Squeezed (HP), and Cold-Squeezed (NOT).
Harsh watercolor paper, as you'd anticipate from the name has the most finished surface, or most conspicuous tooth. It's depicted as having a pebbly surface with a progression of unpredictable adjusted shapes very much like a pebbled ocean side. While utilizing unpleasant paper the paint from an exceptionally watery wash will in general gather in the spaces in the paper, making a grainy impact when the paint dries. On the other hand assuming you dry brush softly across the surface, you'll apply paint just to the raised pieces of the paper, the paint will just touch the highest points of the edges and not in the spaces. Unpleasant paper is by and large not a decent paper for painting fine detail, but rather is fantastic for a free, more expressive way of painting.
HP means "Hot Squeezed" and is the smoothest paper and is appropriate for high detail work. Hot-squeezed watercolor paper has a smooth surface with basically no tooth. Its smooth surface is great for painting fine detail and for even washes of variety. HP is definitely not an ideal surface for amateurs as they now and again dislike the paint sliding around on the smooth surface.
Cold-squeezed watercolor paper is in some cases called "NOT" (as in "not hot squeezed"). It's a marginally finished paper and is the most famous as it's reasonable for most sorts of work. Cold-squeezed paper is a medium, in the middle of among Unpleasant and Hot-squeezed paper and having a marginally finished surface. Cold-squeezed paper is the most ordinarily utilized Watercolor paper as it considers a lot of fine detail work while likewise having sufficient surface to permit an all the more free expressive way of painting.
The thickness of a sheet of watercolor paper is estimated by its weight. So the more noteworthy the weight, the thicker the paper. Watercolor paper is estimated in either (lb) pounds per ream or (gsm) grams per square meter. Most papers have the two loads publicized as standard. There are 4 standard loads of watercolor paper, these are 90 lb (190 gsm), 140 lb (300 gsm), 260 lb (356 gsm), and 300 lb (638 gsm).
At the point when you utilize a more slender paper it should be extended, this is finished to keep the paper from clasping or twisting when you paint on it. How thick the paper should be before it will begin clasping really relies on how wet you will generally make the paper as you paint. The most ideal way to conclude which is the best weight of paper for your canvas style is to explore different avenues regarding various loads to see, however it's probably you'll track down that paper with a load of 140 lb (300 gsm) or less should be pre-extended.
The most effective method to pre-stretch Watercolor paper: In the event that you have picked a paper of 140lb (300gsm) or less the odds are you should pre-stretch your paper. The justification for pre-extending is with the lighter weight papers when you apply water it moves and clasps, or "Cockling". This happens when the utilization of water while painting, will make one side of the paper grow somewhat, the opposite side will stay dry and because of the measuring held inside the sheet won't extend. To neutralize the papers development on the wetted side, the paper clasps and twists. This then causes the unattractive impact of clasping which isn't great for the completed the process of painting, and is likewise very hard to work with.
