Dr. Ph. Martin's Bleedproof White Watercolour Concentrate 

• This is, without a doubt, one of the most recognized and used white inks due to its high pigmentation.
• If you have worked with white inks you will know how difficult it is to achieve an opaque white shade that covers dark surfaces well. That's why Dr. Ph. Martin's Bleedproof White concentrated ink has become a staple in calligraphy and watercolour.
• It is ideal for calligraphy work on black paper or for adding touches of white to our watercolor projects.
• How to use: Every time you use Bleedproof White ink you should check its consistency, adding more or less water until you get a smooth, flowing ink. Add a few drops of water, stir well and check the result with a pen and brush. Repeat, adding more water little by little until you get the desired consistency.
