Rescale

[Revell-Fan]

Alright. I have taken a look at the file you can obtain from here.

A closer examination shows:

THE GOOD

The file is 2690x3922 pixels big. This is a pretty nice size to preserve a hi-res texture. Parts look nice and sharp. So that is a BIG plus.

THE BAD

The resolution is DEFAULT PC IMAGE RESOLUTION which is 96dpi:



This means the image is 28x41" big! The page contains all the parts necessary to build the model. So you need a 28x41" big sheet of paper to print everything properly. Well, to be exact, your sheet of paper still needs to be a bit bigger because your printer will leave a small portion of the rim white. I may be mistaken but I do not know of any sheet of paper which is that big.

THE UGLY

The description says the model is in 1/1900 scale. But how big are the parts supposed to be at that scale?

There is no way you can print such a big image on letter-size paper or A4 paper properly. You have to adjust the resolution of the image file at first. But what is the resolution the designer intended so that the model parts are indeed printed at 1/1900 scale?

To make a long story short: Only he or she knows. There are so many settings possible that it is impossible to determine the correct numbers.

Now let's pretend the creator wanted you to print the page on one page. What did he / she use as determining factor? If you now say, the paper size, this will get yourself into big trouble because there are MANY different sizes of paper. The most prominent ones are letter and A4. Letter is slimmer than A4, A4 is shorter. So if you take this into consideration the parts are not printed the same size if you use different sizes of paper. As a result the scale is off.

In addition, you will need to leave a margin around the image so that everything is printed properly. This makes the parts even smaller. But how big is that margin supposed to be? Again, only the creator knows.

to make the pdf 1:1900 (from 94%) you would have to turn off the fit to page or shrink to fit. and click custom %.
once you do that enter 80.6 in the custom % box. this will reduce the size to 1:2500 scale. at this point, you just have to hit print

How did you determine the printing size of the image when you exported it into a PDF so that the parts are printed at 1/1900 scale? Did you measure specific parts like the diameter of the saucer, compare it with a number of a reliable source and scale the image accordingly on a suitable canvas?

Thanks Ennder,
Just one thing I don't get.
You solved my 1900 to 2500 dought, GREAT!
But will that work with other scales, like 400, 700, 1400, and so on and so forth?
Or, is there a calculation that I can use on any PM?
And also...
I don't understand what the percentage change came from....
As per RF, I was supposed to divide the original model (1900) with (2500) and I got .76 which is 76%.
You gave me the percentage 80.6%.
Where did that percentage come from?

And sorry about all the questions. I ask so hopefully I won't have to keep askin and botherin everyone every time I want to Change the scale of a model.

 

[ennder]

please disregard my previous post. was trying to type and was on the phone.

when you klick the custom it will automatically make it print at 100%. you then enter the .76% that you get from dividing 1900 by 2500
then print. this works in adobe.

OH GADZ! That just thru me for a loop.
I think I'll STAY AWAY from Paragon's models if that's going to be an issue every time.

But how do you know that the scale was 1/1900 in the first place if there is no info given on the size of the canvas which the model was supposed to be printed on?

I'm sorry for that. I tried to build his Wanderer class. The pages of the template were all the same size but even printed at the same resolution they came out in different scales so that the model was unbuildable.

So... From now on.... I save, open in picture 1:1 to see the actual size, and if it is NOT a monstrous model and fits npretty much on the sheet as it is supposed to, I'll do RFs math and print. If it's a monster, I'll just shoot it to Photoshop and EYEBALL the scale reduction.

 

[ennder]

um... a couple of years ago I compared the 1700 NX01 that I had built to the print that I had of the refit

So you basically used strategic elements like the diameter of the saucer and compared it with the size of the part on the sheet? If so, then you did it right. This is the only possible way to make sure that you have the correct scale.

 

[ennder]

one thing I dont like about P's models... is that he wants you to print all the way to the edge of the page. not all printers can do that now days.
back when he was drawing them most printers could print to the edges... if you knew the settings to use.... but not anymore

What do you mean with "open in picture 1:1 to see the actual size"? Does Photoshop display an image at printing size on the screen? For example, if there is a 1"-line on the page which is supposed to be printed 1" long is displayed 1" long on the screen at "1:1"?

 

[Revell-Fan]

@Vahmp : I have added two images with the same object but in two different resolutions. If printed correctly the black rectangle is exactly 1" long. Do both of them appear 1" long at 1:1 on the screen?

Ok... As of right now....
I am so lost, I don't know my a$$ from my elbow. hahahaha
My head hurts. I give up for toda.
I'll try this tomorrow.

yeah, something like that. If I create an A4 page, with the same real time measurements, and open in print size, I can see exactly what it will look like on paper, That's How I do "Eyeball Scaling". lol

I'll do this test tomorrow, ok. With everything going on here plus a 16 year old drivin me crazy, and this scaling issue, my head hurts. So I'll leave it alone till morrow.


Have a great night guys.

Wow, I never thought about doing that.

I'll do this test tomorrow, ok.

I'm looking forward to hearing the result.

No need to be worried. One step at a time. Just don't give up, we'll get this going.

Ok, I'm going to show what and how I do it by fotos....

Ok RF, here's what I do first... What I see in "Print Size" (depending on the image, sometimes I have to make small adjustments, like in the top one of your 2 fotos) the bottom one is the 300dpi (that one to a bit longer to adjust. view foto below) I then creat an A4 page (the one on the left).


Then I do what I wrote on this page.


Next I adjust size of original model (this case, your bars) and transfer them on to the A4 page.



Save it as a JPG file and print.

It's a bit of a hassle but I get this result.
BTW; I readjusted it so now it's correct.
1:2500 exact.

But when it comes to models with multiple pages.... The bit of a hassle becomes a BIG headache.
Wish there were an easier way to rescale.

Mind-blowing!!! Thank you for showing this.

Thanks. But still wish there was an easier/faster way to rescale...
I'm going to keep tryin your way RF, TILL I GET IT RIGHT!

(I added the step that was missing to my explanation)

OH! BTW: FOR SOME REASON, I CANNOT PRINT PDF FILES.
