Discuss the various aspects of heat press technology. Transfer paper, inks, plastisol transfers, vinyl cutters, printers, commercial usage, durability, suppliers, etc.
I have an order for 10 black sweatshirts fabric 100% polyester. I printed the logo and pressed it using the mighty press machine temperture 370 for 20 sec.
The background of the logo is gold in color. After pressing the logo changed color (dark gold) and the sweatshirt has press marks from the presser. I'm very dissatified with the final product.
Can anyone tell me why the color changed and how to remove the presser marks.
What type of process are you using? Plastisol? Opaque Inkjet papers? Heat Transfer Vinyl?
You might be able to help eliminate the press mark by using an oversized teflon sheet over top of the transfer before pressing? When you say presser mark...do you mean scorching or just an indentation? If it is an indentation, try ironing the shirt inside out.

I'm using opaque heat transfer paper. The press marks appears from the heat press machine showing the outline from the presser. I hope I'm clear in describing. It appears as a shadow from the presser. I used the protective sheet which comes with the opaque paper to protect the garment. The outline from the presser still appear and the color from the transfer (the opaque paper) not the ture color.
What type of inks are you using? Sometimes the inks will color shift (I've only personally seen this with normal heat transfers, but I suspect it would apply to opaques as well). If you're using Durabrite, try adjusting your color profiles (advanced print options) to -15 yellow, +5 cyan, +5 magenta.
As far as the press mark, usually this isn't a big deal. If it's really strongly visable, perhaps your pressure is a bit high. Otherwise, you can try pressing the rest of the shirt in an attempt to even it out (make sure you use teflon over the already transfered area) or try ironing it inside out like Josh suggested.
Opaque transfers will change color after pressing. Usually I see that they get brighter. My suggestion is to make a strip of the colors with different variable's of the color and then press on a scrap. That way you will be able to see the one you like. Sweats being the thickness that they are will leave a mark I usually turn them inside out and press. I also press the whole shirt to get even distribution of pressing. Most of the time the marks disappear.

I cant help you with the transfer. But with the press marks, if I have time, I'll press the whole shirt to get rid of the marks. If time is limited, give them a good shake....the marks will lesson considerably after a while although you will still be able to see them. The do dissappear after washing.

Can you look at my post and let me know if this is what you think is happening here. I tried your settings as I am using Durabright and it helped but still has a yellowish tint to much of it.
Using a C88+ with durabrite inks try the following printer settings.
Heavy paper. Text/photo mode. Gamma 1.5 and + 5C +5M -25Y.
Every pic is different the above may not work always and it helps to
print a small scrap pic first on a junk shirt to adjust settings.
Keep pics at 300 DPI, it seems to help.
I am using transfer paper Spectra-Brite.
The attached pic was made using the above settings.
Color change and press mark problems? 
and the sweatshirt has press marks from the presser. I'm very dissatified with the final product.
