The laminator we are talking about is a heated roller setup used to laminate paper or cardboard between plastic. Instead of ironing you run the PCB through the laminator a few times.
There has been some progress in toner transfer. I like the PulsarProFx system others go for Press and Peel (P&P).
The pulsar paper is coated with a starch that turns to slime when wet. The paper floats off the PCB in about a minute. It seems this also allows for a finer line.
To see a quick overview of the pulsar process see . This is an older page. The new (under construction) website says the process is 8 minutes. This is without drilling holes or warming up the laminator.
Frank, the inventor behind Pulsar has a neat etching method where you wipe the copper off the PCB with a sponge and ferric chloride.
The same people also make DecalPro. A system for making carrier free decals in color or foil. Fun stuff.

Coated with Starch? So dusting glossy print paper (or any paper for that matter) with starch and then brushing off most of it would probably help?
P&P is a good product and much better then paper in general.BS!
P&P is as simple, fast, reliable and reasonable.
I would say that all failures are by people that can't follow simple instructions.
The P&P is actual thinner than the average sheet of copy paper! P&P is 0.0025" versus 0.0030" for the paper thickness.
And it is economical and fast to use because no laminator is needed. For the cost of a laminator you should be able to get a lifetime supply.
Nothing gives 'perfect results' just use glossy paper, such as magazine print as suggested. If the toner transfer becomes completly botched scrape off the rest of the toner and start again, but don't do that too many times eventually you will wear the copper down.
There are many ready available petroleum based solvents that dissolve and remove toner in a jiffy, no scraping needed.
The best one (fastest) I have found is "Paint Brush and Roller Cleaner". It is obviously made for oil based paints.

I have been told by people who have used both that the Pulsar will provide a finer line. I think it is because the starch releases the toner while P&P requires you to peel..{snip}

I would not know because I only use P&P and I have no problem with 0,006" lines!
And this is not hearsay.
Is what you are saying that Pulsar is consistently producing lines finer than 0.006"?
firstly thanks for ur replies....
But you all are mainly talking abt pulsar and pnp paper and that is not available here. I have to order it online it costs to me and me not having enough money left now as to spend on that papersas I already spent on the other equipments.
So please suggest me any low cost method.
As Sceadwian is talking abt magazine paper ....
Is it ok for laser printer ??
I think it get stucks in printer as it is not a standard papar(A4 sheet).
Please guide me properly as u all have some experience with PCB designing...

Press it with an iron, but 5 minutes seems too long. I think probably around 3 minutes, but I use a laminator, so have not done it this way for quite some time.ohh man that a very nice trick...Thnx for it first.
Then simply put it on the copper clad and press it for 5-10 min???
Magazine paper leave a good trace on copper clad after peeling it off ??

I would not call this hearsay. The guy who runs pulsar is very up front.Now using any standard 1200 dpi laser printer and the TIA applicator, you can image down to .006" (and below!) We've had customers who have reported traces down to .004"!
Dude as you have experience making PCB by using magazine paper...so can you Please enlist the steps from beginning as I am going to make it for the first time.....
Thanks in Advance
