The all knowing ding is NEVER wrong!!!
Flex your head.
Acetone with pigment tie dye cloth.
Get your head together Kachunka. Acetone ??
That which can be assorted without evidence was read in an illegal magazine.
When I've done multi-tone resin tints I'd pick one color (like a blue or green or tangerine) and go heavy with the pigment in a small amount (like 1/4 oz), another 1/4oz in clear, 2oz in a medium saturation and the rest in a pale tint. Apply the clear first (using a straw to blow or even a fingerpainting technique) and then the medium in whatever pattern or abstract, use the dark to accentuate, and then use the light as a wash over everything else. The wash tints the "clear" less than any exposed foam, so you end up with 4 shades of the same color.
I've also drawn in chalk and then done a single tint over that. The chalk is inert so it doesn't screw up your adhesion. It comes in so many shades that the hard part is picking the shade that will compliment your resin tint.
Complete guess incoming:
Tint some acetone (or use leftover acetone from cleaning previous color work) and saturate cloth with tinted acetone (in a big rubbermaid box or something). Let the cloth dry (tint stays, acetone leaves), then laminate with clear (or light tint). Not positive this is how it's done, and it sounds messy, but that's how I'd try to recreate it.

Greg is correct, a solvent is involved with another clear lam over the graphic. Lots of glassers have done clear 4oz lams over a hotcoat to give the original colored lam more depth, quite common on high-end LB's. This thread from the archives shows the board that Roger "Cleanlines" Brucker did and explains step-by-step the technique https://www.swaylocks.com/groups/marble-abstract-decoration-cleanlines. IMO, the artwork shown in the photos is rather primitive compared to his. The streaked examples are just the way they brushed it and could also be a pigment + acetone technique instead of paint. Roger says even a chimpanzee can do it, and you'll get better results if you give him a banana and cigar. I don't know which one first but it may make a difference.
Whoops. Makes sense and I see how acetone plays into it. The Cleanlines technique is most likely the method. I commented on that thread so it bumped up.
Hi PeteC; what Cleanlines did is on the Hot coat neither of these others are made on the hot coat. Is a mix of techniques done by an Aussie guy; that are killing it right now. He use pigments mixed with tints and solvents all onto the foam or directly in the lamination process or both then sometimes uses posca paints to touch or do small things onto the hot coat.
Then sometimes, as mentioned by others, a tint lamination one color, then clear then other layer of glass with "effects".
Hi Reverb, Thanks for confirming it's indeed color dilution in making those effects. Solvent/acetone "melting" some paint/pigment/posca is what Cleanlines process was about. Doesn't matter if on hotcoat, lam, foam, the same effect is produced with some subtle differences.
I really feel I need to make the following comment to those younger or new builders about board decoration, since this subject comes up all the time. As a shaper/glasser/sander/whatever, the primary objective is function; decoration is much further down the line. Commercial boards (regardless of how they ride) MUST have decoration to set them apart from their competitors to get an edge in sales. Buyers (mostly with low riding skills & money) very often want cutting edge decoration to assert their personalities in the line up, so they will buy the unique; suckers for corporate commercialism. Among the board brands who have drank that kool aid, they believe that all boards today are the same due to machine shaping which is just as stupid as those buying them. In fact some builders have decoration as a primary objective and then try and keep the process "secret" to insure their own sales to retailers. Only about quick money; how long will a brand or technique last based on a secret? This forum has always been apart and free from this crap. Some of the very best in the world are here, and I can confirm they didn't get to that level for the money. You have the freedom to be as unique and creative on board #1 or #1K without any commercialism. So if you see something that interests you, just ask and we'll try and tell you how it's done or maybe how to do it better. But please don't just copy, make it yours. Otherwise you're just that chimpanzee that Cleanlines mentioned with a banana in one hand and cigar in the other. A disturbing image to some, even worse is that some of us old guys at this very moment are holding at least one of those two things.
@petec, well said.
all the best

Yeah Pete, The doc told me to eat a banana a day. Can't do cigars, but Bill Clinton was handy with those Cubans.
