Been in the printing business for over 30 years, this is the most concise and clear video in this subject matter I´ve ever seen. Thank you!

I learned to print on a Heidelberg in Vienna/Austria when I was 16. I had to mix cmyk (HKS) on stone to match a given Color sample and dab it with my index finger on paper, transfer the Color to a plate by hand a.s.o. Long story short - i’m 50 now and I’ve seen a few things since then. I think it‘s pretty dramatic that so many people here on KZfaq can open Adobe Photoshop but never have seen how printing machines in a printing house work but explain this topic along this stupid, confusing opening screen in Photoshop and its DPI/PPI equation. This video is very different to those, you did a very good, high quality job. Kids, listen to this man. He knows.

Admirably clear, concise and complete. I truly salute you! ...If only all clarification videos were of this exceptional quality! Liked and subscribed!

Thank you i’ve had previous problems in communicating with editors and now I understand why thank you so much it’s been very informative

Man, this is the best thing ive found in my whole non-existent knowledge of printing.You'll be big soon my guy I just know it

Education is forever changed. Thank you so much💯

Thanks, great information

Great video, thank you!

Literal best video about this topic

Very helpful! Thank you 🙏

Very informative. Thanks!

thanks for the tip this helped me understand halftones better with screen printing

A very useful information. Thank you!

I change the 240 DPI value in the beginning (from raw to whatever file I need) regarding the end result, the final purpose of the image. But regarding that most commonly I work with 300 DPI or PPI because that allows me to edit the image in a way that it will not be noticed once it is printed.. Most interesting video, well explained sir!!

Amazing video thank you

Thank you so much for this explanation!

Really good breakdown Thanks 🏆🏆

Thank you👏 👍

This was a very clear and informative video - well done!

This was absolutely mega, so well presented and explained - subscribed and look forward to watching and learning more!

Dude your videos are so clear and informative

Your video is everything…just saved me from purchasing a 6400dpi scanner! I’ve been watching vids that say ALL artists need 6400x9600 scanners, nothing less…they don’t explain why and they don’t mention the print factor, paper type, and the reso of the printer! Thank goodness I found this video, thank you!

Thank you thank you thank you ❤🤞🏾

Great info

Very useful video ℹ️ℹ️. Very useful information ℹ️

very informative Thanks sir from Pakistan

top, parabéns vou fazer um vídeo sobre isso aqui no Brasil.

Nice!

Thank you for the well researched! Ahh the art of printing is so different from just web design. so much to learn!!!! gaah

Great

Excellent and very well explained information. And, yes. I change the PS 240 ppi to 300 ppi for EVERY photo edit.

Hi, can someone explain in more depth what he is talking about at 5:45? He says the InkJet look at the information of the PPI, not the DPI/LPI. So when I am creating my files in Photoshop, I would be using what for my resolution if I wanted a clear image? For example, an A4 size paper that is printed from a standard machine like InkJet. This information is a bit new to me, thanks for the help!

To further refine your discussion, "AM" line screens contain "spots" of ink, not "dots" of ink. Each printed "spot" that you see in the "AM" line screen can contain anywhere from 0 to 256 printer dots. "AM" refers to Amplitude Modulation. In my opinion, referring to "spots" inside a line screen as "dots" is equally as careless as referring to pixels on the monitor as dots. See kzfaq.info/get/bejne/brliltGLl7e2Z2Q.html for a full explanation.

Goos that, lad...

Really a great video for the 300DPI myth! Seems this is the ONLY KZfaq video which gives us the correct answer ! But I still have a question about photo printing here: if I have a 7200X10800 pixel file with 300PPI, which people say its good for a 24X36 in print (actually I am not sure if its good enough or overkilled), can I use this file to make a 4X6 in print, and get a better, same or worse print than that big one? Will the printer automatically reduce the pixels (because of too many pixels ) to match the small size, or do anything else? Thanks.

this guy is genius..enuf said

Thnk you I'm looking for info how many PPI I need for A2 Prints. I got 12,16 and 36 Mpix camera and saving for a 45 mpix D850

You forgot ink weight and how that is also very important and is governed by the quality of the stock you are printing on. Newsprint is typically 230-240% total ink weight at #100. Magazines can go up to 300% or more. You also forgot to mention dot gain which goes back to the quality and type of the stock you are printing on. The rule of thumb is what ever the screen ruling of the paper or magazine is being printed at you double the ppi of the image being supplied. This is only true for images that are being reproduced at same size or smaller than the psychical dimensions of the image file usually measured in millimetres, not pixels. When an image is enlarged its ppi reduces and therefore its reproduction quality degrades. Enlarge it too much and you get to see the pixels it's made of. Conversely if you reduce an image its ppi increases. Please note that all of this is being done with in an industry standard page makeup piece of software like Adobe Indesign or Quark Xpress.

If you create a 1080 x 1920 file in photoshop with 1ppi & another at 300ppi. Drop a 1080 x 1920 image. In 300ppi the image is clear, but in 1ppi the image is tiny & blurry. Why so? Can anyone tell?

I used to use Adobe’s recommendation 1.5x the PPI to the screen ruling so a typical photo magazine printed at 133 LPI only really needs a 200ppi image. But try telling that to the client - no chance! The original 300ppi nonsense is the legacy of the first Apple LaserWriter 300DPI printer way back in the mid ‘80’s!

whats the difference btw a 2510 vs 5020 LPI Graphic Tablet? Will you ever notice the difference for professional work?

9:08 wow I really took the time to pause the video just to laugh, that was funny

Sir which photo paper is best for human portrait for 300ppi, 1:Mettalic 2:glossy, 3: matte. Thanks for this very informative video💞💕

How to improve the dpi of an existing image? 🙏 I'm waiting for any way or method including any software.

it very much depends on the media. I print fine art and I can go as low as 182 PPI, although I tend to use 200 as a standard. Some fine art printers go as low as 120 for large prints although I think that is pressing it too much. 300 with a high quality plotter (i.e. a large Epson) is in my opinion a waste of ink.

So.... I ended up here because of the new Epson F170 sublimation printer. Interesting to see this

The PPI needs to be twice the LPI at placed size. I use 400 PPI for FM screening.

Do you have any video on how to get rid of banding in gradients created in adobe illustrator? I increased the resolution to 600 yet the gradient is not smooth.

9:20 WHENEVER did this scenario happen? When ever I was asked for a 300DPI image in all the 20+ years of doing design, It was ALWAYS EXCLUSIVELY for the final image, most likely like a A4/A3 with bleed. If you EVER want to strech the image, you just ask for a 600DPI image from the client. The real question is why can't we all just switch to PPC? won't that be the most logical and easy to use format? Metric system when doing calculations is unquestionably superior to imperial which is only good if you are trading bread and goats.

How much dpi is required to print a large size 30 feet x 20 feet billboard ?

Ok I have a question When I have a 24 inch printer (Canon iPF GP-2000) and I print a large photo 24 inch x 36 inch The printer have 2.400dpi and 1.200 lpi What can the printer really print? 1200dpi = 28800 x 43200 Pixel = 1244.2 Mpx Or 2400dpi = 57600 x 86400 Pixel = 4976.6 Mpx Thx in advance (:

Terms like "2K" and "4K" don’t refer to specific resolutions. They are resolution categories. They are used to classify resolutions based on horizontal pixel count. "2K" refers to resolutions that have around 2,000 (2K) pixels horizontally. Examples include: 1920 × 1080 (16:9) 1920 × 1200 (16:10) 2048 × 1080 (≈19:10) 2048 × 1152 (16:9) 2048 × 1536 (4:3) All of these are examples of 2K resolutions. 1920×1080 is a 2K resolution. 2048×1080 is another 2K resolution. 2560×1440 is not a 2K resolution, it is a 2.5K resolution. "2.5K" refers to resolutions around 2,500 (2.5K) pixels horizontally. For example: 2304 × 1440 (16:10) 2400 × 1350 (16:9) 2560 × 1080 (64:27 / ≈21:9) 2560 × 1440 (16:9) 2560 × 1600 (16:10) All of these are examples of 2.5K resolutions.

thank you sou saved my giant eexam

Beautifully explained. Now can anyone explain why phone & monitor manufacturers are keeping secrets about what the screen is telling the device? On Windows 2000, we could set the exact number of pixels to be shown on screen, and set scaling. Now apparently users are too dumb to have the right to adjust their own screen, hence artificial manufacturer limits are in place, and worst of all, they don't publish what these limits are, so when you install android 12 or windows 10 or 11, the smallest size of icons might be WAY bigger than what you want.

What's you're favorite printer bro? Laser not inkjet because if the ink spread

Pls clear my confusion If I want to print in 300 dpi but my printer is printing in lpi then how many dpi equals lpi?

I've been submitting stills of my film to film festivals that I've entered, and they will invariably request that they be 300 dpi. As explained in the video, they really mean 300 ppi. But this is moronic for a second reason as well: They don't specify how big they intend to print the image. I have a poster that can be printed at 24 x 36 inches, and thumbnails that could be used in a brochure or program, printed at 1 x 2 inches. Both are 300 ppi, but obviously the poster is composed of far more pixels. Requesting a 300 ppi image - even if you use the correct initials - is useless unless you also specify the size it needs to be printed at.

boom math!!

Aren't the real values that matter total pixels wide and total pixels high?

He said a couple of times that raw files are not made up of pixels. This is confusing. Strictly speaking, image files contain 1s and 0s which describe the pixels in the image. Most people would therefore say that they *contain* the pixels. So, *how* are they not made up of pixels ????? Oh, before anyone answers... I'm not a novice. I understand at least a couple of different image file formats.

So, you use 300 ppi just "in case" the printing side wants to scale it?

Super! Subscribe+

so its 300 ppi because peoples images are always cropped in half for magazines ?

Y're engaged

Most of normal folks cant just figure out that DPI is just an instruction to printer at how many dots an inch to print, it' s not a measure of quality of an actual image, actual image quality is resolution 1024×768, 3860x 1800 etc , but the only people that understand it are either gamers or photogrsphy nerds , so every client ever requests files sent at DPI , bunch of sheep 😂

NICE EXPLANATION VIDEO SIR I ALL READY SUBSCRIBE YOUR CHANNEL SIR CAN YOU RECOMEND ME A GOOD 27'' MONITOR FOR PHOTOSHOP EDITINGS & PRINTING? BRAND LIKE DELL VS LG

At 9:22 You’re contradicting yourself. You just explained how PPI is not DPI, then you’re contradicting this by stating that it is. What you mean is that the DPI, even at a high number is resampling whatever file you provide. So blowing up (enlarging) a digital image means you’ll start to see pixels - this is because the high DPI is just showing what is given. In this case a close up of the pixels.

The answer presented tp the question is wrong... 300 DPI/PPI/LPI and whatever thing that you use per inch is the point at which it becomes indistinguishable to the human eye and you need to start using tools to magnify to see the difference. This is not 100% true as different people have different limits but its the reason you want to work with 300dpi, because going under means you are losing sharpness and such and going over means you are wasting resources. "That's not how raw files save those images" is a random statement, repeated, and doesn't belong as you never explain what raw images use. As far as i know they do use pixels/dots and the distinction between the two is really mostly semantic and not worth spending 5+ minutes on. Using TV/Screen resolution here is a real mistake because those resolutions are set, which is why SD/HD/4K all have optimal ranges because as the size of the TV/Monitor changes so to does the DPI/PPI. Ideally you want 300 PPI, but most screens have around 72 to 100 PPI. But because resolution in monitors is disconnected from the idea of resolution when scanning/printing it's really a bad thing to bring up.

WHAT? LOL!

WRONG, WRONG, WRONG! The 300 PPI is demanded for the OUTPUT (PDF) *not* the input image, so AFTER any scaling you would do. 300 PPI is ACTUALLY chosen because of the 'quality factor'. You see, If you put a picture in a digital magazine it is never EXACTLY 150 ppi (or whatever screen value you're using on a press). So, it will be something in that range, say 148, 149.5 or 150.958323. And even if it is exactly 150 PPI, changes are great it is NOT perfectly aligned with the screen of the CTP or press. And what do you get when you have two screens that do not match up EXACTLY? Moiré, a.k.a. interference patterns. The digital information will not translate evenly to the physical plates. What do you have to do to prevent this? Make the screen really, really different, like 1.5 to 2 times higher. THAT'S how we get 300 PPI: the screen resolution (say 150) times the quality factor (ideal 2, higher values are pointless) equals 300. The lowest value is 150 * 1,5 = 225 and the in-between value is 250, the value Adobe has set as default, as a compromise. BOOOOMMMMM, Math! P.S.: I read this in a document by AGFA on printing and scanning in the nineties, they figured this out way back then. You've been doing it wrong for over 15 years, sorry man!

So he didn't explain what is ppi and dpi:/

alot of unnecessary info

I used to use Adobe’s recommendation 1.5x the PPI to the screen ruling so a typical photo magazine printed at 133 LPI only really needs a 200ppi image. But try telling that to the client - no chance!
