My pleasure. Thank you very much :)

Thank you very much. This video was a lot of work too. Makes me very happy you enjoy it so much :)

Thank you very much :)

My pleasure :)

Thank you very much. Let me know if you have any questions - best in my facebook group, because here I often don't see replies to a reply I wrote

Whoever has invented imperial measurements system, and whoever integrated the impedial measurements system into android or any kind of computer is clinically insane and has to stay in an asylum until he dies. It's very clear this has only been invented to confuse people and to make developers who wrapped their head around it appear more "clever" than others. There are hundrets of ways how this could have been done easier, especially without the imperial measurements system. When I see the way most sellers talk to their customers when selling smartphones, I can't believe how degenerate most of this world has become in the recent years. In most situations, neither the seller nor the customer understand anything about this, yet the seller takes an awkward wannabe elegant body posture trying to overplay his retardation. And this is also where the problem is. This system only exists to have a higher amount of sales becouse electronics seem more "magical" if they get missunderstood by the majority of the public. What a load of shit from start to end. How did this even make it through to become market standart?

Yes, that's exactly what i'm saying in this video: The pixel count must be at least high enough to over the size and dpi you wish to print ;)

It's been many years since I worked in the industry (Quark was still the standard), the rule was the required LPI (Lines Per Inch) of the printed material (in the case of newsprint, as low as 60 lpi) dictated the image resolution required, 1.5 - 2 x the linescreen. In the case of newsprint, that meant only 120dpi at the output dimensions. For glossy magazines, often they used something like 120 lpi screens, so a resolution of 240dpi at the output dimensions. Only fine art prints generally used 150dpi, requiring 300dpi. All that assumes screened images, not lineart. Lineart is much higher, 1200dpi or the like, whatever the resolution of the output device could handle. Domestic laser printers and inkjets are a different matter. Inkjets don't print using screens. Also, as Olivio mentioned, billboards are low resolution, as they're viewed at distance.

You are welcome :)

Thank you very much :)

I see why there are so many positive comments now :D

Usually brigther on my phone, but every screen looks a bit different. Maybe your computer screen is too bright or the smartphone screen too dark. also make sure you export the images in sRGB and maybe buy a moitor calibration device to get your screen closer to the "real" color values

DPI does not exist in digital documents! Only the width and height. Even if you have any documents size or formats in 600dpi saving or exporting to a png file it will always say 72dpi or 72ppi. The DPI is a code in a file that tells the hardware (printer drivers) that you want the ink to be printed in a tight or wide paper. DPI or PPI is a imaginary number. You never never save any files thinking in DPI and yes in width and height. 300 DPI is roughly 1000 pixels wide. 1 inch = 300 pixels, so a 4” x 6” image requires 1200 x 1800 px to print at 300 dpi.

@@InteractiveDNA I think we need a cheat sheet of all the combinations one would need to make prints from 2 x 2 to 40 x 60. OS -- are you game to create such a thing or you IDNA? Love the name. I have a sculpture of a Gnome at my front door and I named him Mr. DNA and ask people if they know why. They don't so I tell them that he is a "human's G nome"

Don't worry. It's a hard topic to unravel. That's why most schools simple teach 27 dpi and 300 dpi and be done with it. And in most cases that works. This is more like a "how does it actually work" kind of video ;)

I think you meant to say "the more dots you have per inch" not per pixel. I'm not sure what you mean by "screen line size". Are you still talking about a print at that point or about a screen?

@@OlivioSarikas He probably meant pixels per inch. The number of dots varies per pixel according to the density of colors in each pixel. And there is nowhere you can set it.

In the old days the screens (a piece of film with holes in it)where listed by line of dots in a inch those screens made dots of different sizes depending on how bright the light hitting it. Now all dots are the same and it's how many dots are used to make the same, so the more dots you have to work with the more shades

Also there was a pattern that the screen made for each color so the screens had to laid over your plate film at certain angles to prevent Moray pattern it was called a rossetta pattern

Also still used in non digital offset presses

I don't understand why he thinks changing the DPI to 72 and back to 300 would be nessesary. If you want to create a print at 300 DPI, it makes sense to create 300 DPI canvas and then edit all the images you need in there by placing them or dragging them in. As I show in my video it does not matter what DPI the images you place in the canvas are, as long as the pixel resolution is big enough. AP with then convert them to one 300 DPI document at export for you :)

@@OlivioSarikas Thank you, I have researched dpi many time and was sure I was understanding it till he virtually called me an idiot who didn't know what I was talking about. In the end I just ignored him.

@@norman137 Don't worry about people like that. they are the equivalent of DPI Flatearthers. They heared some stuff and now are hellbend about being correct about it

The screen has a maximum resolution it can display. Is your screen 8K, 4K or 1080p? That is much much pixels it can show. The dpi setting in the file have nothing to do with that. Only the pixel ammount of the file. So check if the image has at least 1920 x 1080 pixels to fill a 1080p screen for example. You can zoom in closer, but you will see the indivitual pixels in that case

@@OlivioSarikas Got it. When i use gradient in creatives design, on some screen it is ok and on some it is pixelated. May be that is the reason

I don't think RPI are relevant to my audience, because not even wikipedia has a RPI entry and I couldn't find anything about that on google relating to dpi or ppi. You are somewhat right about ppi being more important. however a pixel always needs to be converted from or into. A display also doesn't have pixels and needs to be converted to the tech that screen is using. equally a camera sensor doesn't have pixels, the raw data is converted to pixels when you process the raw into a actual pixel format. before that it's just sensor data. but all of that is too specific.

Not the original, but the Candy colored Series when Jobs came back to Apple

First of all: DPI are not literally "dots of ink". There are different print methods and even then a single pixel is made up of different ink colors. That's why we have CMYK and not Millions of Inks. Secondly, I say in my video that PPI are for the screen and DPI are are for print, BUT a 300 dpi image is also a 300 PPI image. So yes, as far as it concerns the file they are exactly the same. That's a fact, no matter if you believe it or not. Oh, by the way, let me blow your mind: Neither a Screen nor your camera Sensor have actual Pixels. That's why the screen has RGB: 3 colors per pixel and your camera sensor records raw data that is only converted into pixels later, either in your camera or in raw development

@@OlivioSarikas Sorry, you are wrong. I love your videos, but as teachers, we are obligated to use the correct terminology. Unless you are a programmer of printer drivers, dpi is completely irrelevant. Yes, there are different printing methods. Some use dots, some don't. But when you are printing with dots, it is still pixels that gets measured out per inch. The printer driver will then take your image, and based on the color density of each pixel in your file, it will decide how many dots that will be printed (and what color) for each pixel. So the only way you can influence how many dots there will be is by editing your image. It is actually pretty easy. Think about a printer with only black. Unless you have a printer driver that decides how many dots that goes into each pixel, you would get a pretty coarse image as a pixel would only be either black - fully filled in, or white - no dots printed (I am assuming white paper). To really get a good greyscale, you would need 255 different inks for an 8bit image. This is a recurring theme with Affinity, because someone there is too proud to admit they have it wrong. Adobe has it correct. There is no mention of dpi in Photoshop. Only PPI. And it is only mentioned in regards to printing. Mentioning color in the answer above confuses your message further. It has nothing to do with either dpi or ppi. And for those printing methods that do not use dots, this is even more an irrelevant thing. Only PPI is relevant. And you should use it in your videos. This is NOT one of these things where we "agree to disagree". Just because a lot of people us the terms interchangeably does not mean that we should go with the flow. Inches is not the same as centimeters. If you had a student that used these wrong, you would correct them. So PPI and DPI are far from the same. THAT is a fact, no matter if you believe it or not.

@@OlivioSarikas Nice video but you are quite wrong that a 300 DPI image is also a 300 PPI image. I just printed a 300 PPI image at 1440 DPI. Understanding the difference between DPI and PPI is very important if you print. For screen display it is not relevant.

That's because it's a T-Shirt and not a Billboard next to the Highway ;)

And still, you'll notice a massive difference, whether you send them a 100x100 pixel image @300 dpi or 1000x1000 pixel image @300 dpi (just random numbers to show my/Olivio's point). The amount of information/pixels you print at 300 dpi is important, not the dpi setting.

@@Thargoran I just follow instructions 😎

@@Thargoran The t-shirt company has it wrong. First of all it is PPI. DPI is irrelevant. BUT - the important thing for the t-shirt company should be the number of pixels in the image. PPI is just a flag (metadata) and it says nothing about the quality of the image. Also, it does not change an imagefile. A 50 PPI image will be exactly the same size in kB or MB as a 5000 PPI image. Give or take a couple of bytes. But as many image banks and printshops actually check the PPI of the image, you can not get around setting it to their demands.

@@OlivioSarikas No. It is because the t-shirt company has a check in place when you upload the picture. In this case, you would be able to upload a 100x100 picture as long as it was set to 300 PPI, but not a 2000x3000 picture if it was set to 150 PPI.

I never said they are and also never said that a pixel is a printed dot. maybe you should watch the video again and actually listen

Are you kidding me? You constantly used the term DPI when discussing on-screen images. Watch your tutorial again, and you'll agree with me.

@@myronachtman4304 I case you haven't noticed: Affinity photo only has a DPI setting, there is no PPI setting to talk about. Go to the Affinity Photo Web presets for example. What does it say? Dpi, right? So, what else can i talk about in this software. Even your digital photo camera will save files with a DPI value, not a PPI value. But on top of that: PPI is what your physical screen has. A file does not have PPI. Just like a file does not have DPI. A 3000x3000 pixel image will look on a screen and print on a paper exactly the same if used in the same size no matter what DPI or PPI you set it to. Also, just to make this clear: I really really don't care if you agree with me or not.

@@OlivioSarikas I also don't care if we agree. I do care about stopping the spread of misinformation. Like you say, PPI setting makes no difference to the size of the image on screen because the screen size and resolution determines the PPI. But for printing it's different. The PPI setting is observed and is one way of setting the image size. DPI has nothing to do with image size or PPI. DPI is the output resolution of the printer, usually set lower than maximum to match the paper characteristics and avoid ink wastage.

There is nothing misleading about the thumbnail. DPI (dots per inch) or PPI (pixels per inch) are specifications that relate to how an image is displayed or printed, not its inherent resolution as a digital file.

@@OlivioSarikas i watched the video now i understand thank you
