Patterns

[kme]

I have been trying to educate myself on seamless patterns.  Many of the video tutorials that I watch start with a document that is 100 px X 100 px, 72 ppi.  Why is this size used so often?

Also, if my original design is perhaps 150 px X 165 px, 72 ppi and I want to adjust it to 150 px X 165 px, 100 ppi is it possible to use the Resample Image to adjust?  Just checking because someone mentioned that this cannot be done...must start from scratch again???

If anyone has a link to an online video or information about making and sizing patterns I would appreciate the info.

Thanks for any help offered.

kme, welcome to PSE&M!

Personally, I would not use more than a 100px square when creating a seamless pattern. However, it all depends on the effect you have in mind.

Here are some tutorials.

Another suggestion. When creating a pattern, create a square and then cut it to size after you can see how the pattern lays on your project. It's not all that easy to make a pattern fit a rectangle and have the design work as you want it to.

Thanks for the response and referencing helpful sites. I will definitely view/read everything mentioned.


This is not a pattern question. Just general question...would you be able to answer?

Also, if my original design is perhaps 150 px X 165 px, 72 ppi and I want to adjust it to 150 px X 165 px, 100 ppi is it possible to use the Resample Image to adjust? Just checking because someone mentioned that this cannot be done...must start from scratch again???

Have a great weekend! Again thanks very much

I'm guessing the resampling in that small of a change should work all right.

Just a question, though - why do you care whether it's 100 ppi or 72 ppi? Those numbers don't mean anything until you want to print. And - realize that 100 ppi isn't going to make any better of a print than 72 - so the change is kinda useless.

Think in terms of pixel size when you create your projects.  ppi is irrelevant until it comes time to print.

For printing, think in terms of pixel size divided by 200 to 300 - 200 is the minimum - but I stick to 300.

So - say you want a 8 inch by 10 inch print.

You would need to start with at least 1600 pixels by 2000 pixels; ideally 2400 pixels by 3000 pixels.

Forget about ppi for viewing on the computer - it's kinda irrelevant in the creation process - and it's confusing as can be.

Can you tell us what you are trying to accomplish?

Is this what you want? You need to change the resolution first. Then, readjust the pixel dimensions.

I am trying to design my own baby blanket. Finished custom knitted size will be 15" x 18". Someone at the company who manufactures these asked me to provide a design sized 150 px X 165 px, 72 ppi. He then said this was too pixelated and asked me to start from SCRATCH..NOT adjust my original design and make a new design sized 150 px X 165 px, 100 ppi.

I am not quite sure what to think??

The blanket will be made using an automated knitting machine.

I am inclined to say you may want to follow the company's advice. They should know if a resolution of 100 ppi is enough.

[cats4jan]

I never understand how these companies think. The machine they are going to use should be telling them how many pixels they want - just that - how many pixels.

I'm not sure what size project they are looking for.

I guess, in essence, what the machine is doing is kinda like printing it out.  

The 100 ppi is most likely a setting for their machine, but it hasn't got anything to do with what you need to provide to them.

But still - asking for ppi seems dumb - all they needed to do was tell you the total pixel height by pixel width needed

If you want an 15 inch by 18 inch blanket and they need 100 pixels per inch (ppi) to accomplish this - you need a project that is 1500 pixels by 1800 pixels.
----------------

I went to 'image resize' in PSE and adjusting the ppi merely changes the finish print size. It doesn't do anything to actually change how many pixels you have in your project.

I guess you could use scale to increase the pixels. When you do that, PSE makes the adjustments by adding pixels you need to increase the number of pixels in your project. PSE guesses which colors to use for each additional pixel to fill in to make it bigger.

I'm not an expert on this - I'm probably the wrong person to be answering this question.

I realize you don't want to start from scratch, so maybe you can rework it using scale.   Which, I think, was your original thought process about how to increase the size.

Hopefully, a real expert will jump in here and help you - like I said - I'm no expert.  I think I'm in over my head because what is being asked of you doesn't make sense to me.  You need someone else to help you.

Sorry.

Sepiana - did you see the total size in inches when the adjustment was made? Her blanket will be 1.5 inches by 1.65 inches.

I'm guessing my thought process is way off. I'm overthinking this.

The knitting machine probably takes the template size they asked for and interpolates it to make a blanket that is 15 x 18 inches. That is the only logical conclusion.

Your method accomplishes exactly what the company is asking for.

It's probably all she needs to do.

Like I said - I'm way over my head and should just bow out of this discussion.

KME - maybe you should ignore everything I've said. I'm probably just confusing the issue.

Janice, hope I'm not sticking my nose in here, but doesn't the motif that they're trying to design to be the repeating pattern on the blanket only have to be in this small size?

[cats4jan]

Not butting in at all. Your concept is right on the money. You probably need give them only one section of your quilt design - thus the small size. Good catch.

That's why I decided to opt out of the discussion - because I don't have a clue what I'm talking about when it comes to designing quilts.

I do, however, still wonder why the ppi parameter when just asking for height/length in pixels would suffice.

Janice,

I am not sure. I was flying blind when I answered kme's earlier post. Only afterwards did we learn the project involved creating a baby blanket using seamless pattern tiles.
