Test pressings (TPs) are used to check and approve the acoustic quality of the vinyl record, as well as to ensure that you are satisfied with the transfer process of the supplied audio onto the vinyl format. You should focus on assessing the quality of the acoustic sound and volume levels, but also listen for any untoward pops, clicks, excessive hiss, and basically any unwanted artifacts that directly disturb or distract from the listening experience. This is also the time to check if any requested record engravings are present and correct.
We provide a minimum of two (or more) test pressings so that you can identify any serial issues with the vinyl pressing. Any consistent serious issues on every copy may suggest a metalwork issue, necessitating the creation of new stampers before the final pressing.
All copies should be the same, but due to the mechanical process of vinyl record production, things like pops and clicks can and will vary from copy to copy. Due to the short-run nature of test pressing production, on occasion the vinyl presses may not have reached optimum temperature for the first few records, so it’s important to listen to all 2 (or more) copies. A test pressing often exhibits more “surface noise” compared to the main pressing run, which consistently presses under optimal heat conditions.
Your turntable’s setup can significantly impact the accuracy of record playback; often, a simple adjustment to the counterweight can significantly enhance playback. For example, if your tracking force is too low, the needle will not sit deep enough in the groove to accurately trace the encoded information. This can result in a perceived loss of frequency, whereas the real issue lies with the playback equipment. Given the multitude of potential errors, it’s crucial to pinpoint the precise location of a problem and identify any misleading impressions.
We recommend that you listen to your TPs on several different set-ups, as there are factors that can affect the way a record sounds on playback. These factors include the type/condition of your stylus, the weight and setting of your tonearm, the speakers, and the room acoustics.
