CD Replication vs. CD Duplication: Which is Right For You?

When it comes to pressing your new album to CD you’re faced with the choice between CD replication and CD duplication. Both pressing formats have their attributes and advantages, so it comes down to which works best for your album and distribution plan. Let’s break it down for you!

CD Replication (AKA CD Pressing)

If you’re serious about your next album and you want the presentation to be as important as the music itself, CD replication is the way to go. CD replication uses a glass master disc for professional mass production. The underside of the disc is a reflective silver, just like the major label CDs you buy at record stores. Our silkscreen CD printing can handle any variation of colours, but even just two colours is enough to make your disc pop. We also apply an AQ gloss to the disc so you won’t leave behind smudges or fingerprints when taking your CD in and out of its case. You can even personalize your discs by adding “pit art” to the unused section of the disc underside.

In other words, if you or your band want to make a big impression, CD replication is the way to go. It is the standard for major label releases and goes a long way in illustrating that you’re in for a professionally produced listening experience. As the lasers on CD and DVD players tend to age and disrupt playback, replicated discs are much more reliable for weak lasers and older disc players. CD replication gives the respect your fans deserve by granting clean and glitch-free playback whether at home or on the car stereo.

CD Duplication

If you’re looking for a small run of CDs to sell as merch at live shows, say less than 250 copies, then we recommend CD duplication. Using your 44.1 kHz / 16-bit lossless files as a master, we duplicate your CDs by hand, undergoing quality assurance checks to make sure there are no transferred errors. Alternatively we accept master discs in lieu of WAV files, wherein we run scans to make sure the disc is clean and safe to duplicate. We duplicate using high quality CD-Rs with a light-green underside, much superior to the discs you would find at your local electronics stores which are prone to errors.

CD Duplication and CD replication have the same packaging options, but for the most bang for your buck take a look at our 2-panel cardboard sleeves. With full colour print on both front and back of the packaging, the lightweight design of the 2-panel sleeves are perfect for touring and bringing from one venue to another. If you need extra space for artwork or liner notes, upgrade to our 4-panel cardboard sleeves or Digipaks, which open up like a book and add two spaces for additional artwork.

CD duplication is also ideal for short-run discs that are intended as promo or giveaways. If you’re distributing PDF files at a conference or sending demo discs to radio stations, sometimes a simple paper sleeve with a window is enough, which you can order from our bulk packaging CD duplication page.

Whichever method you choose, Duplication.com promises excellent quality on printing and pressing with every order. We’ve been pressing and duplicating compact discs for decades, with an eye for detail and extra attention to quality assurance. We’re always happy to answer questions, so don’t be afraid to shoot us an email or give us a call at 1-800-777-1927.

Harmonized Codes for Cassettes, CDs, Vinyl, and physical media!

Closing a cassette mailer

Although the future of Trump’s tariffs now seems uncertain, they are still being enforced and wildly changing the landscape of music distribution. Last week we highlighted that all forms of duplication, pressing, and printed goods are safe from tariffs under the US-Mexico-Canada free trade agreement, a big sigh of relief for us, and for all the North American labels and bands we work with.

While everything has been figured out on our end, you may still have a bit of trouble navigating customs when it comes to your own distribution methods. For example, many international postal services have halted shipments to the United States in response to the tariffs. And how is the typical Canadian bedroom artist supposed to navigate the complexities of U.S. customs when shipping a cassette to a Bandcamp buyer? We’re here to highlight some tips and solutions to making your shipments smoother and safer.

Learn Your Harmonized Codes

Harmonized codes (HS codes) are an internationally recognized system for identifying different product types within the context of free trade. In other words, writing “cassette” in your item description may be a bit vague, but adding the correct harmonized code will tell the custom agent (or AI bot) exactly what your package consists of. This takes a way a lot of the guesswork, and will hopefully move your package through a bit quicker.

Here are a few harmonized codes you may need—

  • Audio cassettes: 8523.29.4010
  • CDs: 8523.49.3000
  • Vinyl records: 8523.80.1000
  • Printed vinyl jackets and sleeves: 4819.50.3000
  • Printed cardboard CD jackets: 4819.50.4060
  • Printed inserts, folders, and booklets: 4911.99.8000
  • DVDs: 8523.49.5000
  • VHS tapes: 8523.29.60
  • USB keys: 8523.51.90

Country of Origin Documentation

To make things a little more official, we’ve gone ahead and created a form declaring the country of origin and media type for your shipment. Just print out the form and highlight or circle the type of product you’re shipping. This form is only good for products manufactured by Duplication.com!

Country of Origin Markings on Packages: Ya Gotta Do It

Given that we’re likely to see a massive influx in package inspections, you’ll want to start taking the country of origin markings seriously. The country of origin (i.e. “Made in Canada”) must be visibly marked on the exterior of your printed package. You can add this in any artistic form you’d like, as long as it’s clean and legible. We also have stickers we can place on ploybags, shrinkwrap, and overwrap. This has been the law for decades now, and while it may have gone unnoticed for a long time, we suspect it will be enforced more and more in the future.

What if You Can’t Ship to the United States?

In response to the end of the de minimis rule, over 30 countries have halted shipments to the United States. This makes shipping Australian punk or Thai death metal albums to American fans a little difficult, to say the least. One solution is to seek out American distros that are interested in carrying your releases. When you order through Duplication.com we can split the shipment, sending a certain amount of stock to your doorstep and the remaining amount to the distro. Now your American fans can order from the distro, you collect your cut, and you don’t even have to visit the post office!

Design Your Artwork the Right Way: A Guide to Print-Ready Files

Refused - The Shape of Punk to Come cassette artwork

We’re always looking for ways to make your Duplication.com orders more efficient. After all, you filled out the cassette duplication quote form, or purchased printed goods from the online shop, now you just want the product in your hands! We’ve realized that back-and-forth emails about album artwork has a tendency to slow down order production, which is why we thought it would be a good idea to share some pointers on how to optimize your album artwork design and delivery!

“Where do I upload my files?”

The age old question. The answer is pretty simple though: after you submit a quote request or buy a product from the online store, you will see an upload link on the file confirmation page. If you missed that, you’ll also find it in the confirmation email. This link will send you to your private FTP folder where you can upload both your audio files and artwork files. It’s best to zip the audio files and artwork files as separate folders, with easy to understand file names.

The Art of Print-Ready

A print-ready file is exactly as it sounds: a digital file that’s formatted correctly and ready to print without the need of further adjustments. Here’s a short checklist:

✅ The file should be in CMYK color mode
✅ 300dpi resolution
✅ Fonts are either embedded or converted to outlines
✅ Bleed has been added to ensure that there’s no white trim around the image
✅ Export to a PDF format (Photoshop users: export as Photoshop PDF)
✅ It’s helpful for us for you to label the file with the application you used (ex. jcard-front-photoshop.pdf)
✅ For templates such as J-cards, CD covers, etc., please provide us with two files: one with the template lines, and one without the template lines.

Save As Adobe PDF

This may seem like a lot to a first-time designer, but we promise you that this is the industry standard for printers worldwide. If you follow this checklist, we most likely won’t need to hound you with questions, revisions, or the dreaded resubmission fee.

Country of Origin markings

If you open the newspaper you may be surprised to learn that shipping items across the border is an absolute freakshow right now. Fortunately we’ve got things settled and figured out on our end (check out our post about that for some very useful info!), but there’s something we need from your end: the ‘Made in Canada’ marking.

While we have an Ohio production facility, the majority of our print is still currently coming from our Toronto factory. This means it’s necessary to add ‘Made in Canada’ or ‘Manufactured in Canada’ to the outside of your package. It used to be that a batch of 100 cassettes could pass through the border uninspected, but given the tariff madness, those days are behind us. Don’t be a fool, don’t have your package sent back, just add the marking!

Now there’s a number of subtle ways to do this: you can always design your artwork to include “Made in Canada”. Use whatever font you want, and at whatever size, as long as it’s legible and visible in the exterior package. You shouldn’t have to squint or use a magnifying glass to see the text.

We also have stickers that can be placed on the package or the shrinkwrap. In fact, if you add shrinkwrap and Made in Canada (MIC) stickers, by default we’ll be placing the stickers on top of the shrinkwrap unless requested otherwise. Stickers are available in black or white print, and the option will be added to the cassette duplication form soon, just hold tight!
