Pcb silkscreen?

im gonna try etching my own pcb but i want to know how to put a silkscreen on it and the mask to keep from short circuiting

Silkscreen printing is usually used on the back of the PCB to label where components go... and is only necessary when making kits or when you need to label mass-produced PCBs for easier diagnosis and repair. If you're doing your own, you don't need to worry about that.

As far as masking the areas you don't want to etch away: There are multiple good instructables already on that topic. What do you need to know that they don't explain?

(Unless you're asking whether one could apply a mask by silkscreening. Sounds like a reasonable idea, but again unless you're tooling up to produce a lot of these it doesn't sound like it would be worth the effort.)

i want to make them look more professional and not bare copper i didnt know if i could like dip it into something and that would work or not
A professional PCB *is* generally bare copper on the conductor side, possibly still covered with resist at points other than the contacts.
And short circuiting is prevented by simply etching the right pattern into the copper cladding and then not letting solder or wire or anything else bridge gaps that they shouldn't. Silkscreening isn't involved in that.

Easy way to silk screen - Print your silk screen 1:1 - cut out - position over the manufactured circuit using a couple of holes to locate then glue down. Paper glue will do.

i could use resin though right or would the heat malform the pcb

The MASK these days is usually deposited photo-chemically, rather than screening.

Hot glue!
